Product catalog summary

General Workflow Overview
Create surface, volume, and graph meshes in Materialise 3-matic. Export these meshes as .fem files, which are then imported into HyperMesh for Finite Element Modeling (FEM) and Computer-Aided Engineering (CAE). After processing, export the results as .fem files and import them back into Materialise 3-matic for further design refinement.

Mesh Creation in Materialise 3-matic
In this example, only surface and graph meshes are created, with graph nodes connected to surface or volume meshes. Assign thickness to graphs before exporting, with options for gradient, image-based, or uniform thickness.

Exporting Meshes
1. Navigate to File > Export > FEM.
2. Select the part and output directory.
3. Choose which meshes to export and apply the settings.
4. Check the .fem file if necessary, which includes lists of mesh nodes (GRID*), mesh triangles (CTRIA3), graph edges (CBEAM), and graph sections with thickness (PBEAML).

Importing .fem in HyperMesh
1. Go to File > Import > Solver Deck.
2. Set the file type to OptiStruct and import the file.
3. Use basic controls for inspection: Ctrl+LMB to rotate, Ctrl+RMB to move, and Ctrl+scroll to zoom.
4. Switch between solid and wireframe views, toggle tags, and change mesh color modes for detailed inspection.

Exporting .fem in HyperMesh
After completing FEM/CAE, export the results to a .fem file:
1. File > Export > Solver Deck.
2. Set the file type to OptiStruct and use the Long format template.
3. Export the file.

Re-importing .fem in Materialise 3-matic
Requires Materialise 3-matic 10.1 with the Remesh module:
1. File > Import Part.
2. Import the relevant meshes.
3. Confirm the import to continue design work, with shape and thickness information preserved.
