Hi all,
I'm modeling gas-liquid two phase flow with eulerian model, at the beginning ,the simulation goes well,but when i load a drag coefficient, there is an error after about 50 steps calculation : Floating point error: invalid number Error Object: () I've tried to decrease the under relax factor, it seems not useful.what should i do? Thank you for your answer in advance  zoesjtuer Last edited by zoesjtuer; April 15, 2010 at 10:46. |

Initiating the case with wrong conditions may lead to floating point error when the iterations start.
and also wrong boundary condition definition might cause the floating point error |
