Volume meshes are widely used in simulations for mechanical, fluid, thermal, electrical, and other applications.

This module is:  

• An easy-to-use tool to create accurate and high-quality tetrahedral volume meshes directly from CT scans for use in third-party FEM simulation software
• Based on subvoxel-accurate, locally adaptive surface determination*
• Based on algorithms that work directly on the volumetric data of the CT scan without creating an intermediate surface mesh, thus maintaining maximum geometrical accuracy
• Suitable for scans of mono-material and multi-material components or material probes

*Coordinate Measurement module required 

You can control and improve the finite element (FE) mesh quality according to specific element quality requirements by setting target parameters for mesh optimisation.

Choose from one or more of the following criteria: 

• max./min. element size,
• edge aspect,
• edge/height aspect,
• collapse,
• stretch,
• shape factor,
• smallest face corner angle,
• largest face corner angle,
• and min. edge size.

Histograms for each quality criterion and the ability to visualise the criteria in the mesh allow you to review and assess the mesh quality clearly.

Macroporosity can be represented geometrically in the volume mesh by treating the border of the macro pores as internal surfaces, which are respected while meshing. Additionally, the microporosity can be mapped onto the volume mesh as a volume fraction of micropores for each mesh cell and exported in .csv format, which can be directly imported into, for example, Digimat for further use in an FE solver.
