Hello everyone,

I am a Master Student using SU2 for my msc thesis. I am trying as a first step to run a steady state simulation of a one row rotor stage using the turbomachinery tool. I am having an issue with the nspan of the outlet and looking for the fault on the forums I found that is maybe related to a partitioning error of the mpi capability, but when I tried running the simulation with one core, the fault remains happening. I also saw that the nspan can be manually specified somewhere but I dont know where. I attach a screenshot of the fault. Thank you in advance

Hey there, probably there's something wrong with your mesh. Have you tried solving one of the test cases, a 3D centrifugal compressor case ? Probably that case will run at least without mpi.

Hi koray,

Thank you for your reply. Definitely it was a mesh issue, but I have not found where the mistake comes from yet. I have 3 volumes, all created with TurboGrid at the same time, and the first two volumes work fine but when I include the third one it crushes
