Error

Hi guys,

I'm a newbie in feflow and fepest.
I did the demo excersise for fepest and everything worked fine.  I inserted for calibration a model that I had previously created in feflow and when I try to save it as a fepest project, make checks and run it or even close the fepest program then I am taking back the error invalid argument passed and I really can't figure out what is going on. Can u please help me???? :) :) :)

Thanks in advance

Sounds like a license issue... Pls. check whether you run with a valid license or in DEMO mode (in the latter case with a small model only).

Thank you for your response.

Actually it was the path name(written in greek) that was creating the problem.

Have a nice day!!!
