hi
Dear Alexey,
Finally, program gave again following floating point error:confused:. Mass flow, velocity inside of nozzle seem OK, but at the inlet pressure are increasing so excessively.
Also inside of error i recognized that time step cont. error became crazy?? what is the meaning of this error and how can i correct it?
Thanks in advance.
