Default hanging nodes in fluent;

When I try to import hanging nodes into fluent it gives the following error:

Reading Cell Tree: failed while reading section 58.

Clearing partially read grid.

Does anyone have an idea how to solve? I generate the mesh with ICEM CFD. First it was giving the error of "uncovered faces". I solved it with the grid check menu of ICEM. However, fluent didnt accept the grid.

thanks anyway Zafer

Hi!

What is the ration of hanging node? Fluent ignore the 1=>2 ratio. but if the ratio is more than this, you have to merge them in ICEM, before you export to .msh

Thank you for your reply. In my case the refinement goes from 1 to 2. I think the problem is in my solver. However, in the case I use fluent, do I really just leave the uncovered faces unfixed (for example, without rebuilding the topology) and just export the .msh file?

I also read solutions that imply the doubling of faces and nodes at the interface, I was wondering if this is a solution that is usually used.

If these solutions don't work for me I will surrender with the polihedra interface (via "resolve refinement").

Thank you guys

Hi!

If your solver is fluent, just export the mesh and run if the ration is 1 to 2. Don't care about the uncovered faces!
