Hi,

I am trying to generate a smooth mesh transition between a quad and tetra mesh for a 3D geometry in order to align the nodes. The quad mesh is generated by sweep method. I have tried edge sizing but it just messes up the interface. Is there any other way to generate a smooth transition, or am I simply misusing the edge sizing control?

Thanks!

Hi Krihamm,

When you were generating the geomerty, have you shared topology between the different parts of the body ? enabling shared topology in the geometry will help you get exactly what you want. The nodes at the contacts between the zones will be linked.
If you need more information on how to enable shared topology, let me know.

Hope this will help.
good luck

Hi Annan and thank you for your reply!

I did not implement shared topology before. Now that I have all nodes connect. However I failed to mention in my previous post that I want the different mesh sections to have different sizes, i.e. I want a very fine mesh around parts of special interest and then want it to be more coarse further away. I realize this could be done by adding edge sizing, but I also want it to transform from tetra to quad. Implementing shared topology just seemed to reduce the element size of the larger elements so they would match the smaller ones.

Do you have any suggestions how I could change the element density to gradually decrease between two sections of tetra/quad mesh?

Actually I got it working now Instead of implementing shared topology I just grouped the different parts into one part in geometry. Seems to be ok now!
