stuck at floating point exception for dynamic meshing with an udf in fluent

      i want to simulate the pitching of airfoil in still medium,after some iterations i got the floating point exception error ,dont know where i was going wrong,can anyone help me out?

      Look at the results shortly before the model fails. Is the model well converged, and is the airfoil still at a sensible angle of attack?

      A floating point exception normally comes from an error at a core when you try to do something impossible with a floating point number, like divide by zero. If you look at your console output before the model fails, you'll probably see warnings about some variable reaching a limitation.

      first of all thank you for ur reply sir,


       i was dealing with transient case,yes the solution is converged and after some iterations i got this error.i was doing my analasys in still medium (0 velocity) so i didn't concerned abt the angle of attack.

      If there's no flow what are you monitoring? 


      @cvelikonja  correct, and it's a shame I can't like your comment.
