Euler -Lagrangian issue

ibadullah safdar · June 17, 2016, 17:17

Dear all
I am doing a flow analysis through a venturi tube. I have three phases i.e. air, water and particles. So when I used the Euler-Euler approach with air as a continuous phase and water, particles considered as a dispersed phase then I have obtained the fine results. But I also want to do the tracking of particles with Lagrangian approach to see the difference in results but there is an error occurs i.e.

ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Floating point exception: Overflow

So what is the problem. Plz sort me out I shall be very thankful.
