Floating point exception in Solidification/Melting with VOF

I am modeling Laser melting of a solid block using solidification/melting and VOF. I am using Explicit VOF to track the interface between the inert gas domain and the metal. Following are my parameters:
Courant Number(Explicit VOF) = 0.8 Global Courant Number = 0.8 Adaptive time stepping with initial time step size = 1e-7 s Compressive scheme for VOF discretisation. Mesh cell size = 1e-5 m with all hexahedral cells My solution starts and shows very good convergence initially. After around 22 %, it shows "floating point exception" and stops although convergence criteria is still satisfied. Can someone please help in this matter? |
