Hello,   I'm having issues with the Region interfaces while working on a new heatsink model. The Interface Generator tells me that there are 6 faces, which are candidates for more than one region interface. I have 3 Physics regions in this model: The air around the heatsink, the air inside the heatsink (which is completely seperated from the external air) and the solid body of the heatsink itself. The problem seems to occur because of the interface between the internal fluid flow region and the solid region. I already used the "Imprint" option in the geometry editing and all Problem areas were fixed, so there are no more problem areas found. I also made sure that the fluid volumes don’t overlap the solid volumes, everything is cut out / enclosed correctly. In addition I also checked for gaps, missing faces etc. and there is nothing to be found. Changing the tolerance in the interface Generator also does not help. What other options do I have to fix this issue?   Thank you in advance

Hello Martina_Mohr

Its difficult to offer any suggestions in this case without looking at the model. I will send you a link to upload the model.

There were some geometry-specific issues which were leading to region interface problems. Repairing the geometry helped to resolve the issues.
