CFD on Multiple buildings

hp_010 · Posts: 2

Hi,

I am trying to run a external CFD analysis on multiple buildings. It's a reasonable big site with some 10 buildings of which 9 high rise. I tried it first with two buildings and it worked. With 10 buildings I tried multiple times to find a grid that worked. When i finally did find a grid I get an error message when i try run CFD caluclations indicating an invalid cell aspect ratio. I could upload it but it's quit big, 12 MB.

How to proceed?

Thanks,

Harm

Hi,

You could try increasing the grid line merge tolerance which should decrease the cell aspect ratios.
