 | CATIA FEM Surface 2 (FMS) provides an advanced mesher for automatic and associative generation of a finite element model on surface parts and wireframe geometries. Based on a powerful topological engine, it provides advanced control for the generation of the finite element, saving significant time. You can generate finite elements for assembly joints, including spot and seam welding among other fasteners, and analyze the mesh quality according to pre-defined and customizable criteria. The FMS product provides the power that the specialist desires for manual mesh editing. Features - Provides new methods for topological interpretation
- Provides powerful control for surface and wireframe mesh generation
- Provides the correct mesh features to match the specific type of analysis
- Provides customizable quality analysis of finite elements
- Provides dynamic mesh edition and flexible quality reports
Key customer benefits - New methods for topological interpretation
Interprets part geometries and provides the most intelligent topology supporting the placement of elements best suited to the type of analysis to be performed. These intelligent algorithms reduce the preparation time of the model by dramatically reducing the amount of elements that must be manually edited.
- Advanced surface mesher
CATIA FEM Surface 2 (FMS) provides comprehensive surface mesh capabilities to address complex surface parts. The mesh part is associated to the surface geometry from which it was created and any modifications to the surface geometry, and will drive a new mesh part. FMS provides controls to maintain the topology to generate a surface and wireframe mesh that is acceptable to the most discriminating analysts. Throughout the meshing process, the referenced geometry is never modified. The mesh works with an exact replica of the geometry as a clone, respecting all the geometric characteristics, and adapting those characteristics to the needs of the mesh, without impacting the original design geometry. The result is an automatic and easy-to-interpret display of the meshed geometry.
- Control and touch up meshing
Local constraints can be applied easily and quickly, permitting you to drive the meshing of complex surface parts. These constraints can be applied directly to the geometry or to the nodes and elements. In addition, local element sizes can be assigned to the geometry prior to meshing. You can detect intersections or collusions of meshes, which is especially useful in large assemblies with multiple meshes.
- Flexible and customizable quality analysis
You can automatically visualize the quality analysis results directly on the mesh. Elements not conforming to the selected criteria can be grouped for the purpose of modifications. Using full mouse editing, you can dynamically update quality analysis results on the mesh and also move nodes on geometry, edit finite elements (splitting, swapping, etc.) or smooth the mesh. The auto-focus capability saves considerable time by automatically identifying the various areas to be improved.
- Flexible quality analysis reports
Reporting of quality analysis results is provided in charts and text. You can filter information provided in the report by quality criterion or finite element type. If quality criterion is chosen, you can obtain the percentage of the mesh's finite elements that respect the threshold value for each criterion. When sorted by finite element, you will see the results of the quality evaluation for each finite element. This capability enhances communication between individuals or teams, which is especially important with large part assemblies.
- Mesh offset
The mesh offset is integrated into the meshing phase. You can position the mesh according to the neutral fiber, saving significant time in part preparation.
- Joint technology
Generation of finite elements for assembly joints including spot and seam welding is supported with the joint technology based on non-compatible elements. You can modify and adjust weld locations without impacting previously generated meshes, which preserves the integrity of local area meshes undergoing extensive modifications.
