Product Description

CUBIT is a full-featured software toolkit for robust generation of two- and three-dimensional finite element meshes (grids) and geometry preparation. Its main goal is to reduce the time to generate meshes, particularly large hex meshes of complicated, interlocking assemblies.

Product Highlights

Meshing: CUBIT is a solid-modeler based preprocessor that meshes volumes and surfaces for finite element analysis. Mesh generation algorithms include quadrilateral and triangular paving, 2D and 3D mapping, hex sweeping and multi-sweeping, tet meshing, and various special purpose primitives. CUBIT contains many algorithms for controlling and automating much of the meshing process, such as automatic scheme selection, interval matching, sweep grouping and sweep verification, and also includes state-of-the-art smoothing algorithms.

Geometry Preparation: One of CUBIT's strengths is its ability to import and mesh geometry from a variety of CAD packages. CUBIT currently integrates the ACIS, Granite, and Catia geometry kernels directly within its code base, allowing direct manipulation of the native CAD geometry format within CUBIT. This reduces the errors and anomalies so often associated with geometry translation. CGM also boasts a facet-based geometry kernel developed at Sandia that can be used for remeshing or editing old mesh files or models defined by triangle facets. In addition, CUBIT has developed a comprehensive virtual geometry capability that permits local composites and partitions to geometry without modifying the underlying native geometry representation. The user can choose to ignore, clean-up or add features to the model allowing greater flexibility to meshing algorithms to generate better quality elements.

CUBIT Environment: CUBIT has developed both a convenient command line interface with an extensive command language as well as a polished graphical user interface environment. The GUI is based upon the cross-platform standard QT, which allows the same look and feel on all supported platforms. Also included is a graphical environment based upon the VTK graphics standard which has been optimized for display and manipulation of finite element data and geometry. Fast, interactive manipulation of the model is a tremendous advantage for models with thousands of parts or millions of elements.

Meshing

New Triangle Mesher
CUBIT 12.0 includes a new triangle mesher based on a hybrid approach of parametric advancing front and Delaunay technology that has shown huge speedups in triangle meshing. This mesher is extremely fast on spline surfaces whereas the previous advancing front mesher worked in 3D space and was extremely slow on spline surfaces. The scheme for using the new mesher is “tridelaunay”. However, the user can utilize the best of both tri meshers by using the “trimesh” scheme which causes CUBIT to choose the best mesher based on the surface type.

Edge Length Smoothing
CUBIT 12.0 contains the most recent version of the Mesquite smoothing libraries (2.1) which include an edge length smoother that tries to make all of the mesh edges on a surface the same length. This has shown to be effective in getting rid of small edges in a paved mesh that drive the analysis time step down too small. An example of this smoother is illustrated in the pictures below. The picture on the left has small edge that have resulted from the paving algorithm. The picture on the right has enlarged the small edges to be much closer to the specified mesh size.

Edge Length Quality Metric
An edge length quality metric has been added in CUBIT 12.0. This allows the user to analyze the all of the edge lengths on surface meshes and output/plot the results just like any other quality metric. The pictures below illustrate the edge length improvement in the above problem using the new quality metric.

New Commands for Creating Free Mesh

The user can now generate 3D mesh elements by extruding, revolving, and offsetting 2D elements. The commands for doing this are shown below.

Create element extrude [node|edge|face|tri] <element_list> direction (options)

[distance (options)] [layers]

[twist (angle) axis (axis_options)]

[along curve <curve_list>]

Create element offset [face|tri] <element_list> [(normal_to|opposite_normal)]

Create element revolve [node] <element_list axis (axis_options) angle (angle) layers (num_layers) attempt_hex_fix

Examples of extruding along a curve and revolving are shown below.

"View at" Mesh Entities
The user can now use the “view at” command on mesh entities as shown below.

[View] At {body|volume|surface|curve|vertex|hex|tet|wedge|tri|face|node <id_list>}

Moving a Node
The user can now move a node using the “direction” options as shown below.

Node <range> Move Direction <options>

Mesh Pillowing
Mesh pillowing is a mesh refinement technique that inserts a layer or 'pillow' of elements around the boundary of an enclosed mesh. It can be used to improve mesh quality while preserving the outer boundary of the selected element set. Mesh Pillowing can be used to quickly perform a number of meshing tasks, such as inserting a uniform boundary layer a specified distance from an outer boundary, or inserting a ring of elements around a hole. An example of using mesh pillowing to add boundary layers is shown below.

Skinning

“Skinning” of volume meshes to generate a shell of surface elements was added in CUBIT 12.0. The result of skinning a tetrahedral mesh is a set of triangles and the result of skinning a hexahedral mesh is a set of quadrilaterals. The commands for skinning are listed below.

Skin {Hex|Tet|Block|Volume} <range> [Make {Block|Sideset|Group} [<id>]]

Skin {Hex|Tet|Block|Volume} <range> {Add|Replace} {Block|Sideset|Group} <id>

Tet Meshing from a Skin

The ability to tet mesh a set of triangles was added in CUBIT 12.0. This capability is often used in concert with the skinning ability described above to “remesh” the interior of a volume mesh starting from the boundary mesh. The commands for doing this are shown below.

Tetmesh <triangle_range> [Make {Block|Group} [<id>]]

Tetmesh <triangle_range> {Add|Replace} {Block|Group} <id>

Remeshing

The ability to “remesh” a set of tetrahedral elements was added in CUBIT 12.0. This can be used to improve the quality of an existing mesh. The syntax is shown below. Only the “Remesh volume” command existed in CUBIT 11.1.

Remesh {Volume|Block|tet} <id_range>

Geometry

ACIS Upgrade

In a continuing effort to provide the best capabilities from ACIS, CUBIT 12.0 contains an ACIS upgrade to version 19.0.2. A version of CUBIT 12.0 containing ACIS 17.0.2 (the last version of ACIS that CUBIT used) will also be made available temporarily for Linux users still running Linux Redhat 4 as ACIS 19.0.2 is not supported on Linux Redhat 4.

New Preview Options

Preview options have been added to most of the commands associated with moving and copying geometric entities. This allows the user to see the result of the operation before actually doing it. All of these new options are available in the command panels associated with each command as shown below.

The new commands that contain the preview options are listed below.

Sweeping to a Target Body

CUBIT 12.0 includes the ability to seep curves and surfaces to target bodies rather than having to specify a sweep distance. This makes specifying the sweep criteria much easier. An example of sweeping a curve to a target body is shown below.

The command syntax for sweeping to a target body is shown below.

Sweep Surface <id> Target Body <id> [Direction {options}] [Plane {options}]

Sweep Curve <id_range> Target Body <id> Direction {options} [Plane {options}] [UNITE]

General Way to Specify a Location
The ability to specify a general location on a plane “close to” another location has been added as shown in the command below.

[On] Plane <options> {Close_To|At} Location {options}

Moving Geometry Using a General Location
The ability to move geometry using a general location specification has been added.

Move {vertex|curve|surface|volume|body} <id_range> [Midpoint] General Location <options> [preview] [except [x] [y] [z]]

Idealizing Holes/Slots/Fillets in Surfaces
The following commands have been added for idealizing features within surfaces (sheet bodies). These capabilities are ideal when working with midsurface models or sheet body assemblies.

Tweak Surface <id_list> Idealize {[Hole Radius <val>] [Slot Radius <val> Length <val>]} [exclude curve <id_list>] [preview]

Tweak Surface <id_list> Idealize Fillet Radius <val> {[internal] [external]} [exclude curve <id_list>] [preview]

Tweak Body <id_list> Bend root <Location> axis <direction_vector> direction <direction_vector> radius <val> angle <val> [preview] [keep] [center_bend] [Location <options>]

"Max Area Increase" Option when Tweaking Curves
When tweaking curves the user now has the option to control the extent of the tweak by specifying the maximum area increase allowable during the operation.

"Thickness" Option when Tweaking "Doubler" Surfaces
When working with sheet body assemblies (often a result of midsurfacing) it is often necessary to connect two “parallel” surfaces by dropping down side surfaces from one of the surfaces to the other as shown below. When thickness properties are stored on the surfaces the user now has the ability to propagate the thickness property to the new surfaces that are created during the operation.

Auto Midsurfacing
In CUBIT 12.0 the midsurfacing capability has been equipped with an “auto” option to automatically locate surface pairs for midsurfacing so that the user doesn’t have to specify them manually. The picture below shows the results from issuing the following command: “create midsurface volume 1 auto delete”. The matching surface pairs for the midsurfacing operation are automatically located and the result is shown on the right.

New Option when Stitching Sheet Bodies
CUBIT 12.0 includes a new option when stitching sheet bodies. The “no_tighten_gaps” option allows the user to specify not to do the “gap tightening” operation which is the final step of the stitch operation. The ACIS modeling engine can sometimes fail the entire stitch operation simply because it failed the “tighten gaps” step. With the new option the user can tell ACIS not to do the “tighten gaps” part of stitching which will often result in better success on very large or complex models.

New Functionality when Copying Vertices
Two new functionalities exist when copying vertices in CUBIT 12.0. First, names are now copied when copying a vertex. In the past names were only copied curves, surfaces, volumes, and bodies. Second, the vertex copy command now includes the option to move the copy of the vertex after creation. The new syntax is shown below.

Vertex <id_range> Copy [Move [X <dx>] [Y <dy>] [Z <dz>]]

Miscellaneous

CFD Boundary Conditions

The supported boundary condition types in CUBIT have been expanded to include the following common CFD types

Inlet Velocity

Inlet Pressure

Inlet Mass Flow

Outlet Pressure

Far Field Pressure

Symmetry

Periodic

These new types are supported in the Fluent export format

Export Formats

CUBIT 11.1 supported a full set of FEA boundary conditions for Abaqus, IDEAS, and NASTRAN. Version 12.0 expands this list to include Patran Neutral, LS-DYNA, and Fluent (Fluent also supports the CFD boundary conditions described above).

Boundary Condition User Interaction

Command Panels. The command panels for boundary condition creation/modification have been updated and reorganized for easier navigation and use. Support for the new boundary condition types has also been incorporated. The figure below shows an example of the new command panels.

Graphics and Selection. Graphics window support for boundary conditions has been greatly enhanced allowing the user to now select and interact with boundary conditions in the graphics window just like they would other entities.

Selection filters similar to those for geometry and mesh entities now exist for selecting both FEA and CFD boundary conditions (see below).

Tree View. The boundary condition portion of CUBIT’s tree view has been enhanced to support display and interaction with physical boundary conditions. The boundary conditions are divided into groups associated with FEA and CFD as shown below. Blocks, side sets, and node sets are located under the FEA group.

Boundary conditions can now be selected and interacted with like anything else in the tree. Right-click context menus are available for drawing, listing, deleting, and performing other operations on boundary conditions. Selecting a boundary condition in the tree will cause it to be highlighted in the graphics window.

Properties Page. Boundary condition properties show up in the Properties Page when selected in the tree or the graphics window (see below).

Materials

GUI support for materials has also been added in this version of CUBIT. Materials can be created/modified in the command panels and interacted with in the tree view. Below is the panel for creating materials.

Win64 Platform

Windows 64 bit was added to the list of supported platforms in CUBIT 12.0. The list of platforms now supported is shown below.

Linux 32- and 64-bit

Windows 2000/XP (32-bit)

Windows 64-bit

Mac OS X

Qt Upgrade

CUBIT’s graphical user interface is built using third party libraries called Qt. Part of the “refactoring” effort this year included upgrading CUBIT’s graphical user interface to use a newer version of Qt (version 4.5.1). This brought with it a number of benefits. The new version of Qt has an updated look and feel, supports native Windows Vista controls, and the latest and greatest Mac controls. However, just as important are the non-visible benefits. The new version of Qt makes doing many of the user interface niceties easier and provides for better long term maintenance of the user interface. Further, the licensing structure for developers using Qt in the newer version allows for all of the developers to use Qt without having to obtain a license. This allows more of the developers to develop with the Qt environment which flushes out problems more quickly and leads to a more robust product.

Re-architecting

A significant amount of effort has been spent re-architecting portions of CUBIT in anticipation of future research and development. Specifically, the interface between CUBIT and the mesh it generates/modifies/exports has been cleaned up to allow CUBIT to interface with a generic mesh database that will support much larger meshes and will allow CUBIT to be used for parallel meshing research and development. These changes do not show up as benefits to the user in the short term but will enable significant advancements in future releases of CUBIT.

Modularization

The CAMAL library contains meshing algorithms that have been extracted from CUBIT and put in a form that can be used by third party applications. CAMAL version 5.1.0 is being released in conjunction with the 12.0 release of CUBIT. The following meshing algorithms have been modularized and are included in CAMAL 5.1.0:

Curve Meshing

Surface Mapping

Surface Submapping

Surface Tri-Delaunay Meshing

Volume Mapping

Modularizing these algorithms makes them accessible to third party applications that want to take advantage of the CUBIT capabilities directly in their code. Furthermore, it enhances the maintainability of the CUBIT meshing technologies.

Beta Features

Cubit remains an active development platform for cutting-edge methods in geometry preparation and mesh generation. Some features that are still under development may not be quite ready for release, but may be valuable in some settings. The following is a list of new beta features that have been made available in Cubit version 12.0. Their functionality is not yet complete, has not been fully tested, however in many settings the new capability may be very valuable. Your help in reporting defects and offering suggestions on these features is appreciated. To turn on or off any of the features listed below, issue the following command from the command line:

set developer [on|off]

Wedge elements: The ability to import, export, display and create a wedge shaped element has been added. Wedge elements may also be generated when generating free mesh be sweeping or rotating. Wedge elements can also be generated in some pillowing operations.

Geometry Tolerant Mesh Generation: The ability to automatically suppress features in a model has been added. Given a size tolerance, features smaller than the tolerance will be omitted from the model and the finite element mesh will ignore the features. This capability will create free mesh elements unassociated with the original geometry. It is currently available for tet, tri and quad meshing.

Limitations in CUBIT 12.0

IGES and STEP import functionality is not currently available for the 64-bit platforms.
The Granite Geometry Kernel is currently not supported on Mac OS. As of this release, PTC has not announced plans to support a Mac OS version of Granite.
The Granite Kernel supports most of the commands and options used with the standard ACIS implementation in CUBIT. See the Granite document in the users manual for a description of differences between the CUBIT's supported options between Granite and ACIS.
The Mac OS X port does not support the changing mouse cursors on pre-selection It is recommended that a 3-button mouse be used for the Mac OS X version since interactive transformation utilize all three buttons.
Smoothing the interior nodes of a free mesh only works with the (default) equipotential smoothing algorithm. The Mesquite smoothing algorithms do not currently function with free mesh.
Nodesets and sidesets are not necessarily maintained after a refinement operation on a free mesh.
