Hi everybody
I have started the boiling flow simulation (RPI model) in a rod bundle system. First I did it with the mono approach and I obtained convergence. After that, I have tried it with the poly-dispersed approach. But my simulations stop after some iterations with this error: c_fpx_handler: Floating point exception: Invalid Operand.
What I have tried: different time scales (smaller), different turbulence models, coarser meshes, checking the BCs. But I could not prevent the error.
Do you have any recommendations?
Many thanks
