| ERROR #004100018 has occurred in subroutine FINMES. | | Message: | | Fatal overflow in linear solver.

hi i run my analysis using k-epsilon turbulence model and after 9 iterations, above error ocuured. i mesh my model in Gambit and using boundary layer as follows;

-first layer thickness = 0.0001 m -expnasion factor = 1.2 -layer = 20 layer

can anybody give me an idea..

Hi,

Your simulation has diverged. Look in the documentation under obtaining convergence.

As a quick fix: Did you try adjusting your timestep from automatic to manual?

Divide the recommended auto time step by 10^3 and try it again.
