Hello everyone,

I am trying to model flow of liquid Aluminium through packed bed of NaCl particles, I am using Euler-granular model, k-epsilon turbulence model.

The model initiates well, however at certain point during calculations, the pressure is disturbed and I get error "floating point exception"

I initiate the model at the following parameters

Liquid velocity: -15 m/s
Packing density= 0.7

I am using velocity inlet and pressure outlet. I am not really sure what is going wrong, I attached some screenshots of the time step at which the error takes place.

Thanks in advance
