Meshing method for topology optimization in OptiStruct
Altair Employee Hi,
I would like to mesh a 3D part with only cubic elements (jacobian = 1) and then I would like to perform topology optimizaiton. Could you please explain me the difference between classic and voxel mesh? How would the final result look like if I use:
a) HEXA mesh
b) voxel mesh

Altair EmployeeThank you and what's the difference between these two types of meshing, computing and results?
Altair EmployeeResults are better with Hexa mesh but it is not possible to capture all details with pure hexas,

Voxel meshing and computation is faster compared to hexa, but the accuracy is poor
HI,
This type of mesh is only useful in topology optimization. It does not give meaningful results in a stress analysis.
