HVAC, solidworks flow simulation

Madeinspace · October 29, 2014, 10:46

I am trying to analyze flow simulation and comfort parameters using solidworks flow simulation in a relatively bigger classroom (40*30*3 m^3) with 30 diffuser as an air-conditioning inlet, many heating (surface source) component such as PCs and ceiling lights and students themselves. However, every time I run the simulation it stuck in prepare modelling. It has been stuck for more than 4 hours and I terminated it. My laptop has i7 processor with 8gb of RAM. Is the computer capacity not enough. In order to get preliminary result, I haven't considered several effect such as mesh refinement, heat conduction in solid and radiation. What seem to be the problem here?
Please suggest.
Regards

Hello,

Have you resolved your issues?

If not may be good idea to share your model, I can check it on my workstation.

Regards

Oh, I haven't seen your post. It might be related to a bug that existed at that time. I'm not sure. I think I heard something that this can happen. It is definitely nothing about the computing power. At this stage the geometry is exported to the mesher and this is like saving the files so not in anyway RAM related. RAM related problems would appear during the meshingn or solving if the mesh is too big for the RAM you have available.
