FEM Utilities for CATIA

FEM Utilities for CATIA delivers CATIA V5 analysis users a set of tools aimed at bridging the functional gap between the analysis products of versions 4 and 5 of CATIA.
 
Key Functionalities

General

  • Support of journaling
  • Access all capabilities via VB Scripting
  • Full integration with KnowledgeWare

FEA gateways

  • Supported formats are:

- NASTRAN Bulk
- ANSYS Prep7

  • Capabilities:

- import and export of linear structural FE data
- support of GPS local beam and shell properties
- support of assembly of analysis documents
- support of FEA user numbering if present in the model
- support of multiple load cases and solvers
- support of data mapping

  • Limitations:

- no post-processing support
- no composite or thermal analysis support

Manual meshing

  • Full support of spec – update paradigm:

- “Manual Mesh Part” feature used to group manual operations
- each manual meshing operation is captured in a feature
- advanced nodes and elements selection capabilities enable stability of selection during the updates

  • Meshing operations on nodes:

- creation by coordinates, by selection of an existing node or by transformation of existing nodes
- deletion of nodes
- modification of position by specifying new coordinates or by applying a transformation
- condensation on destination nodes

  • Meshing operations on elements:

    - creation by selection of nodes, by extrusion (nodes, edges and faces) or by transformation of existing elements
    - deletion of elements
    - modification of the normal of surfacic elements, split of quadrangles and hexahedrons
  • Limitations: no support of assembly of analysis

Semi-automatic meshing

  • Three families of capabilities:

- mesh part operators used to modify the result of a mesh part
- meshing by transformation of an existing mesh (including symmetry)
- meshing by extrusion of an existing mesh

  • Very flexible input specifications:

- input mesh selection by mesh part, group, BRep or mechanical feature
- implicit geometry characteristics can be used (e.g. the axis of a cylindrical face)

  • Supported transformations are translation, rotation, offset, along a curve and projection

Numbering of FEA data

  • Through this capability the user is able to control the numbering used by the FEA interfaces when exporting data.
  • Limitations:
    - no support for topological numbering
    - no support of Undo / Redo (will be lifted in the next release)

Logical operations on groups

To perform logical operations on groups of nodes or elements: input data can be any feature capable of selecting nodes or elements, mesh parts, BReps and mechanical features.
