I want to provide a voxel-based file or tetra grid mesh geometry for analysis in solvers like Abaqus. always generating tetra mesh face with different errors like the following figure. Does anyone have such an experience?
It is not easy or (sometimes even) possible to get rid of these type of errors in avizo which is generally suitable for use of visual purpose. You can write your own code or change your software for voxel based mesh generators which are not cost effective.
