CFD Online Discussion Forums - Floating point exception

Hello guys,

I am trying to run a simulation of a heatsource placed inside an airconditioned room. i used the rhoPimpleFoam solver. my mesh quality is good ( hexahedral meshes) and checkMesh showed no problems at all. but on running the simulation i am getting the following error:

Code:

rho max/min : 3 0.3

bounding p, min: -1e+06 max: 3e+06 average: 1e+05
