Set minimum set size

Is it possible to control the minimum tet size? Here is my work flow for meshing:

volume all scheme tetmesh
volume all size auto factor 10 propagate
mesh volume all

I get warnings of tets measuring under 0.2 and when I ignore the warning and run the mesh model in Abaqus I get extreme distortion on the small tets.




Auto factor 10 is the coarsest setting. You are likely to get the poorest mesh quality at the largest sizes. You could try setting the size smaller.

Another option would be to try the Geometry Adaptive Sizing. It will take longer to mesh your model, but the mesh size will change based on feature size. There are a number of controls that can be tweaked, but the defaults work pretty well.
