FEM Utilities for CATIA

FEM Utilities est un logiciel intégré à CATIA V5 qui s'intègre dans les ateliers de maillage et de calcul de CATIA V5 (Advanced Meshing Tools & Generative Structural Analysis).

​

FEM Utilities est un logiciel de type "add-on" qui vient enrichir les solutions existantes de CATIA dans 3 domaines principaux:

            - le maillage (manuel et automatique),

            - le pré et post-traitement,

            - les interfaces avec des solveurs externes éléments finis.

Fonctionnalités de maillage

​

Manual meshing

Meshing operations on nodes:

    - Creation by coordinates, with two existing nodes and a ratio,...

    - Deletion of nodes

    - Modification of position

    - Condensation on destination nodes

Meshing operations on elements:

    - Creation of 1D, 2D and 3D elements

    - Deletion of elements

    - Modification of elements

Full support of spec–update paradigm:

    - “Manual Mesh Part” feature used to group manuals operations

    - Advanced nodes and elements selection capabilities enable stability of selection during the updates

​

​

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

    - Input mesh can be nodes, 1D elements (or edges), 2D elements (or faces) and 3D elements

    - Implicit geometry characteristics can be used (e.g. the taxis of a cylindrical face)

Supported transformations are translation, rotation, offset, along a spine and projection

Opérateurs  de maillage

Pre/Post Processing

​

Numbering

Through this capability the user is able to control the numbering used by the FEA interfaces when exporting data.

Logical operations on groups

Throught his capability the user is able to perform logical operations on groups of nodes or elements. The inputs can be any feature capable of selecting nodes or elements, mesh parts, BReps and mechanical features.

​
