After a 15 month break I am back trying to solve my wing . I downloaded the latest version - can run the RANS solver on the ONERA sample . when I load my own SU2 mesh then it does not even start the solver iterations - see attached. The Mesh worked on the earlier SU2 so I am again stuck . Any help appreciated.

I can't understand why it crashes, but it seems that Mach and Reynolds numbers differ between the configuration file and the output

I am starting to think the problems I am having are related to machine size . The mesh is quite large with over a million elements and running on a core i7 PC on virtualbox with 30gb partition and 16gb memory ??

Does anyone have a correlation chart between mesh size and resources needed ?

Unfortunately I never did such analysis. Did you just run the SU2_MSH to see if the mesh is read correctly?
