how to do after Floating point error is told

September 22, 2007, 23:39

hi,all i is using VOF technique to model fluid free surface under over 101500 pascal.Under-relaxation factors are 0.3 or 0.1, first order upwind,using k-epsilon model, my computer tell me:

Updating solution at time level N... done. physical-dt 1.0000e-005 iter continuity x-velocity y-velocity z-velocity k epsilon time/iter

reversed flow in 2287 faces on pressure-outlet 8.

Error: Floating point error: invalid number

Error Object: ()

i want to know that i should deal with flouting point error?
