Reply To: ANSYS fluent – Rocky DEM coupling

[Saeed]

Hello, 

I have doubled the size of my geometry and meshed with cartesian mesh method , I ran the fluent , then I used that case and dat file to couple with Rocky, when i load the dat or case file there is no errors . but when I start the simulation, after initialization, i recieve the floating point exception error. I ran the same simulation with the small geometry with no problem, their only difference is that I used the multizone mesh for the small one. 

Can you please help me with this? 

Thanks
