Hello, I have a mesh file in .cgns and some input data. I need to make cfd config file and run it. Here are my mesh and cfd, but something is wrong with them: i got an error while solving it. Please help me to sort out with it.

The error occurs while the processing the solver, and there are not any information about what caused this problem.

Hi Nikita,

for me the case runs with your provided files. Can you give more information on the error you get ? Maybe posting the output ?
