I had the same issue just make sure that in the folder that you have your FEpest file every other file name or parent folder name is written in latin characters

Thank you for your response.

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

Have a nice day!!!

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
