Streamwise Periodic Solver
 

I am trying to run a Streamwise periodic simulation, almost identical to the one in the tutorials. However, I have recreated the mesh using my own scripting abilities through GMSH. The geometry is identical to the tutorials however it is unstructured and using triangular elements.

My simulation will not run past the 1st iteration, outputing a residual over 10^20. I don't know what I'm doing wrong, if it's either the mesh or the setup.

The mesh is set with the left side as the Inlet, right side as Outlet, top and bottom surfaces as symmetry and the cylinder surfaces as cylinderx (x=1_3).

I'm attaching my config file as well as a picture of the mesh and the history output.

without having looked at your case: are the periodic interfaces "matching", i.e. all nodes on the "inlet surface" can be found on the "outlet surface" connected via a constant translation vector.
I think SU2 would mention a potential mismatch, but this is also just a first question.
