Default Divergence of residuals

Posts: n/a
hi everone

When I start the iteration, the residuals after very 1st iteration show a very high range, between 1e-1 to 1e+6 and then after second iteration the values reduce to a smaller range between 1e-1 to 1e+1 . But after a few more iteraions it shows following error ..

Error:> (greater-then):invalid argument [2]:wrong type [not a number]

Error Object:nan0x7fffffff

Previously I was using a different mesh and for the same schemes and initial values, the solution was converging well. But then, I refined the mesh further and am facing this problem. Can this error be because of defect in the mesh? Please help.

I am using vof implicit scheme to study flow aroung a ship model. ( )

Thanking you. Manoj.

Is it possible to change the range of acceptable values of the residuals, so that the error doesn't comes and the iteration continues further.
