Error #001100279

Dear all I'm working on ANSYS CFX in order to solve the flow around a low pressure turbine. I'm a beginner of ANSYS CFX I don't understand the error that I have had after the running CFX some the ERROR #001100279, but I don't understand the reason.

Can somebody to explain to me what is happened?

Thanks in advance

Domenico

Your simulation has diverged. Try starting with a smaller timestep or possibly a local timescale factor. Once it has started converging then you can wind the timestep up (or return to physical timescale if you used local timescale).

Hi c120613,
I think you made mistake with material settings or mesh units setting.Note that the inlet velocity 8.2678E+03 m/s.So the mach no is more and it results in Solver failure.
