Bug with Implementing Internal Surfaces in SU2
Hello Everyone,
I’m having an issue implementing internal surfaces in SU2. It appears there is a bug in the software that is causing this to not function correctly.
I have a simple channel geometry that runs with no issues as expected. However, when I define two internal boundaries, “internal1” and “internal2”, without changing anything else in the simulation, the simulation mysteriously crashes after about 20 or so iterations.
This is the marker that I’m using:
MARKER_INTERNAL= ( internal1, internal2 )
Both meshes, and the .cfg file I’m using along with a few images for reference can be found using the following Dropbox link:

Any assistance would be greatly appreciated.
How was this mesh made? If I remove the internal interfaces from the mesh, the simulation still crashes. So the mesh that contains the interfaces is not created in a correct way.
If the mesh is made with pointwise, the nodes at the internal faces are duplicated and there is no connectivity across the internal markers. I have not found anyway to fix this in pointwise but I think you can write a small program to remove duplicate nodes and renumber the rest.
