Continuus meshing on surface

I have problem with a frame, showed below.

I would like to have single shell mesh on this frame, but Ansys every time treats it as consisting of many elements, not just one. How can I create single shell mesh in Ansys Workbench?

For generating shell elements, you could convert your solid bodies into surface bodies. See this tutorial:

I did this. Actually, I created surface model already in inventor, so midsurfacing wasn't needed. All I want to achieve, is something like this:

Hypermesh continuus surface meshing

Continuus surface mesh, as shown above. This mesh was made in hypermesh.

 

The problem is, that when I solve this model as it is, I do not get propper stress propagation. This construction is welded, so stress distribution should be continuous, but it is not.

Would you be able to share your geometry?

Sure.

 I haven't looked at your geometry as I was creating a small example that has two bodies that have been meshed, and a mesh connection connects them. There are two ways to plot the stress, Average Across Bodies set to No, which is the default, and Average Across Bodies set to Yes, which is what you want.

You can upload files to posts if they have a .wbpz or a .zip file extension and are < 120 MB. There are many other valid extension.

I think this solves the problem. Thanks!
