For topology optimization, the mesh should be homogeneous in order
to be able to represent the inner surfaces during the redistribution
of the material. Nevertheless, if the homogenity of the mesh needs to
be improved, in ANSYS® Workbench
this can be achieved using the Patch Independent meshing algorithm
as shown in the following figure.
If the minimum and maximum element sizes are chosen in a small range,
a homogeneous mesh is generated inside the volumetric parts, which is
more suitable for a topology optimization task. The figure below shows
the mesh for topology optimization.
