Free Tetrahedral

Fill selected solid domains with tetrahedral elements for finite-element analysis.

Where to find it

Mesh workspace → Free Tetrahedral

How to use it

Choose Free Tetrahedral, then select the new or existing feature in Model Builder. Build the geometry, choose the domains, select a preset, and use Maximum element size to resolve small geometric or physical features.

Result

Inspect the element distribution and counts before running a study.

Troubleshooting

A mesh can be valid but too coarse for your quantity of interest. Compare results on a finer mesh and check element/DOF limits before a large solve.
