Hello Everyone,

I'm trying to simulate a cyclone to estimate efficiency and pressure drop values. I have got sufficient convergence for pressure drop (could'nt say the same for particle behaviour) but solver crashes in every run.

Details;

1- Mesh contains 4m tetra elements and inflation layers on walls. ( I tried diffirent mesh densities)

2- 10 different size particle described at setup, solid particle size variation 5 mic to 150 mic. Particle density is 3000 kg m^-3. One way coupled, fully coupled or both definition tried.

3-) Continuous phase is air @ 25 C

4-) SSG Reynolds Stress used as turbulence model, k-e, SST also tried

5-) Steady State analyses with different time scale and also automatic time scale had been tried.

5-) Transient analyses with different time steps had been tried

6-) Boundary conditions; mass flow outlet, pressure inlet, no slip wall


In steady state analyses I have got that message;

ERROR #001100279 has occured in subroutine ErrAction
Message:
Stopped in Routine Get_FCI_INFO


In Transient analyses, solver just said that;
CFX solver exited with return Code1.

Finally I got to say that; There is no abnormality seen in backup results and on solver monitors.


Any idea will be appreciated.

Thanks,
Altan
