Title: Simulation
Post by: rafael on December 03, 2013, 03:18:02 pm
When I try to perform the simulation of a fire in a toy store, the following message appears me.
I can not send the file to the forum for being too big.

Usually this kind of problem can be fixed by making changes to how the model is set up. Do you have any powerful vents or large fires? Are there any "interesting" areas that are split across two meshes? Is there a chance that the pressure is becoming very high or very low?

Do You have any OPEN vents? Even if You have only mechanical ventilation You should add one small OPEN vent anyway. Lack of it causes problems with pressure, in other words your model probably is too hermetic.
