I am trying to run twoPhaseEulerFoam for a turbulent multiphase flow case with kEpsilon model, but I keep getting sigFpe error (I think) on the first time step.
I have made sure that the initial k, epsilon, alphat and nut fields are non-zero.
If I switch the simulation to laminar, it proceeds just fine; but if I switch either one or both phases to turbulent, I get the error below.
(Eventually, I want only one phase as turbulent)

I have even tried running the simulation laminar for an initial time period, and then later introducing the non-zero turbulent fields (k, eps,...) and switching the simulation to turbulent. I receive the same error.
If I understand correctly, this seems to be a divide-by-zero error, but I do not understand where/how is it dividing by zero.

Does anyone have suggestions where to look?

hi

does anybody find the answer?

i have same problem.
if use default turbulence model, the solver run correctly. but when i want change the turbulence model to the other possible models i find this error.


so please help me how can i solve this?

Get another version of the same error for nuEff. Any ideas?
