Hello, I have a model that I cannot compute the volumetric region for I get the error 

Warning : No regions computed.

Check for leaks and self-intersections in the mesh.

 

done

 

 

 

region-name number of baffles zone ids of baffles

 

-------------------- -------------------- --------------------

 

external baffles 14 (21 20 19 18 17 16 15 14 13 12 11 10 9 8)

 

I have run all available diagnostics commands but still cannot compute the volumetric region.

I believe it may have something to do with leaking geometry but I cant seem to find anything that's causing the problem, has anyone come across this before? Any help would be much appreciated

It says that you geometry is not watertight. I has a leak and Fluent Meshing can not find a single closed volume. 

Please check your geometry if it has any holes or some missing component.

thank you for your reply, I have gone into spaceclaim and found the source of the error
