How to create perfect mesh transition from coarse Hexagonal elements to fine mesh?
I am testing a structure in ANSYS APDL that includes several cubes attached to each other. Two of these cubes are much thinner (in the middle) and I would like to apply fine mesh on them. However, for the beginning and ending cubes, I would like to have coarse mesh. Please see the attached picture and also you can copy and paste the code to generate this geometry.
If I want to use hexagonal elements, my ideal mesh transition method is like the following picture:
So, first of all, I apply the fine mesh to my thin cubes
So, the final mesh for the selected volumes becomes like the following picture:
So now, here is my question. Does anyone know how I can apply that type of mesh transition (2nd pic) to my model? Because now, the only transition I could apply to this model was using tet elements.
I appreciate any help you can provide.
