I don't want to do auto Mesh, because auto mesh doesn't coincident nodes at contact interface. I would like to generate mesh like figure. Can you help me in this regard, please?
Hi Imrose, most probably this mesh was prepared at first as quarter mesh of the surface. To do it give same number of elements for two radii and circumference and you obtain such kind of butterfly mesh. Then mirror twice. And at last you can extrude your mesh for desired thickness. Sincerely.
Ali is correct. You can try what he is telling. I have done similar mesh around a crack tip during my UG thesis. However, I don't have ANSYS installed in my laptop right now.
There is a glue option in ANSYS. You can use that to combine nodes at interfaces, if in case you use auto mesh. For example, if you create 2 different areas attached together, glue those 2 areas first, then mesh them. It will ensure single node at the interface. However, if you do not glue the areas, meshing will create 2 nodes at the same position at interface. Hope you understand.
That mesh was generated from a quarter part. That quarter part was divided into three portions (two outer, identical and one inner, the quarter part of an octogone) then glued. Afterwards, a parametric meshing with the desired partition on the edges... And therr you have!
Thanks for providing information. Actually, I understand how to generate this mesh but I can't find exact option at ANSYS Mechanical. Can anyone give me a step by step procedure?
