Anyone there help please!
While I'm loading newly generated fem, the log message shows up" Warning math: argument domain error in fuction acos!"
I tired to smooth mesh file then, the warning message is gone, however, I've notice all the faults, river in mesh is not in right place any more after smotthing the mesh. (as there are lots of faults, river need to be noded), this message doesn't show always, sometimes it's disappeared when loaded again; sumtimes it's on!
"totally depends on feflow mood" :-\"
How can I get rid off this warning math message! it would never show up again!
