Hello everybody,

I am new to ICEM so be kind with me.

In my geometry, I have different surfaces and I assigned them to different parts (see Screenshot 1, showing the surfaces in different colors). I did that in order use the parts for boundary condition definition later in CFX.

However, when I display the mesh shells, two little "patches" are assigned to the wrong part (see Screenshot 2, showing the mesh shells). I have no idea where this comes from, because the surfaces are correctly assigned.

Does this come from the blocking? The curves and points used to fit the blocking are inside other parts, separate from the surfaces.

If you need some additional information, let me know. I would be very happy if somebody has an idea about the cause and how to correctly assign the mesh to the parts.

Thanks!

Hi philalama,

it does seem that way, that in the blocking is source of this issue.
Usually, the underlying surface is matched automatically correctly.
In some special cases such as yours, you need to provide some stricter settings to tell the mesh algorithm which block should be mapped on which surface.

Right now the blue mesh in the orange part surface are blocks that were (probably automatically) associated to the blue (surface) part.
You can test my hypotheses by displaying the blocks in the project tree. The blocks in question would have the color of the blue part, and not the color of the surrounding orange part's blocks.

I suggest you to move blocks to a specified part. You should find this option in the context menu of that part in the project tree.
Then remesh, export,... and so on.

This should fix the issue, if i understood the problem correctly.


Best,
Sebastian

Hey,

thank you very much Sebastian. Your assumption was correct, some block surfaces seems to be matched to wrong geometry surfaces.

I was able to solve the problem by using the Mesh Repair tool, which has function to automatically assign shell elements to surfaces. Running this tool correctly assigned the mesh to the parts I wanted, so for anybody else having this issue, this is the easiest way to solve it
