Hi all, I'm using Gambit v2.3.16 and I've some trouble in drawing a particular geometry of an industrial reactor vessel. In fact inside this vessel there's a big wall perforated pipe.

I've to extract negative volume from this geometry and gambit does not consider holes geometry.

I tried with subtraction and with splitting operation without positive results.

Do You have any suggestion?

Thanks for advice,

Best regards

Adriano

I need to extract the internal fluid volume to perform a CFD simulation. The application is in biodiesel production. No aircraft wing applications!
