You can use the new Volume Meshing Module to create accurate and high-quality tetrahedral volume meshes from your CT scans which you can then use for mechanical, fluid, thermal, electrical, and other FEM simulations in third party software. It is based directly on the subvoxel-accurate surface determination* for single or multiple materials in your scanned components or material probes and requires no intermediate surface mesh—thus avoiding the loss of geometry information.
Covering the complete workflow from CT scan to volume mesh, the software generates high-quality, solver-ready meshes. For each selected material component, a tetrahedral mesh with congruent tetrahedron faces and shared nodes at material interfaces is created. The geometric accuracy of the volume meshes for each material can be flexibly adapted and there is the option to create a finer mesh for a particular Region of Interest. The mesh quality can be assessed using statistics for tetrahedron count, shape parameters (aspect ratios, radius ratios, dihedral angles), and sizes. Export the generated volume meshes in the .pat (PATRAN®) or .inp (Abaqus) format. Each cell of the generated volume mesh can be loaded with additional information which may be required for simulation, such as fiber orientations, fiber volume fractions, porosity volume fractions **, or gray values.
