when I did simpleFoam kEpsilon, the error occurred... I don't know how to solve it -.-

Here are my 0 and system folder and give me advices..

thanks

Hey blue

Can you upload the whole .log file of your simulation please? And possibly upload the whole case including the /constant folder (if it is not too big) on a link (i.e. dropbox)

Kind regards

Dear jeytsav. I fixed this problem to change relaxation factor.

But I have questions. when i plotted Cp ( xFoil vs RAS solutions), I can saw big difference near x=0.2..

Is it mesh problem?? or schemes?

p.s) i don't have dropbox.. so i cannot upload /constant
