floating point error
Hi,while running 2D problem with multiphase (air and water)I came across the following error using k-e rng ,vof-implicit model Error: Floating point error: invalid number

Error Object: () i've been getting these errors for so many combinations...plz give me some suggestions.Thanks.Mavinakere.

Re: floating point error
Try altering the under relaxation factors for whichever residuals are 'blowing up'. Also, if its an unsteady simulation (as it probably should be), try decreasing the time step a little.

Re: floating point error
i tried altering the underrelaxation factors and then i get convergence detected in AMG solver kinda error.And my problem is with steady no time steps at all.though i want to solve unsteady ,i get errors in the initial level(at say 20-30 iterations)plz give me more parameters to check with.thanks.

Re: floating point error
A) Use double precision B) Use different mesh size DC
