Hi all. I have a Problem by generating conformal mesh between a pipe and the fluid inside in a conjugate heat Transfer problem.

The model is an Input from nastran-file mit 2mm meshing. I used only one pipe as a small model and I generate the Volumen inside using existing surfaces. (First I duplicate the part and then delete the unnecessary surfaces to form the inside volume) Everytime when I apply the same mesh Setting to all regions, which means the 2 regions are Input part in automated mesher, there's always a error message (see Picture below) that a certain part is self intersecting.

What's wrong with the Methode that I used to generate the proper mesh? What is the right way to do so?

Thank you all in advance

you have not imprinted the two parts to create contacts surfaces which then turn into region interfaces
but i worry when you say you deleted a surface - both parts need to be closed volumes and you can test this by just meshing each on their own - if this works and you have the contacts then you should not get intersecting surfaces unless the imported surfaces do in fact intersect and you can check that in the surface repair tool
