Geometry size problem

Hi all,
I've been trying to run some simulations on a full-scale geometry which is about 20mx10m with some things inside. The models I chose are steady, ideal gas, coupled flow, gravity, turbulent (k-epsilon), axisimmetric. The kind of sim I'm trying to run is a 2D natural convection with a volumetric heat source with gravity vector pointing towards -x. If I try with this model, either I get some error of overfloat, or it simply diverges. If I try the same with a really downscaled geometry, everything works fine. I thought it could be a mesh problem, but all me attempts failed as well. Any ideas? Since I have to study some heat transfer, I'd like to avoid any reynolds similarity etc, since I'm not very used to that kind of thing. |
