hi

i am trying to simulate two phase flow with heat transfer. when i try to start a simulation apears an erorr. it says: Floating point error: invalid number

What does it mean floating point erorr and how to correct the inputs.

thanx

to long time steps, not enougt iterations per time step, some errors in boundary conditions (like , in case of . - I had such problem with , and. beetwen numbers). Please use search. There was such problem on forum many times ...like Ralf said. best wishes
