Re: inflation
 
hi,

you got to read the error message carfully and then hightlight the region of error ,and in that surface give appropiate mesh controls and it will be fine.

Some times you have to play with the mesh control numbers - mesh size

hope tihs solves your problem

Re Inflation
 
Hi, quite often if you can produce a volume mesh without inflation, but can't with inflation it can be due to either two surfaces being too close together for the correct amount of layers to be included - this should be easy for you to check. It could also be due to some rogue CAD geometry which has produced a poor surface mesh, which does not allow inflation to be produced. You can use the CAD quality checker to highlight poor surfaces. Hope this helps.

Thanks for TheOneOnTheRight's advice. Could you tell me where I can find the CAD quality checker in the CFX 5.5

Thanks again

No problem, its in Build under Tools\CAD Quality Check.. It will only allow you to do this after you have completed the domains form.
