If you have used or are using CFD tools like ANSYS Fluent or ANSYS CFX, then you already know how much of a pain extracting the fluid volume can be from a CAD model. Whether the extraction fails because of geometry issues, or if you’ve forgotten to create capping surfaces for all your openings it can be quite frustrating when you get the “non-manifold body” error.
We’ve done it the same way for a long time – create some super solid and do a Boolean subtract or try to close everything off and try to use a cavity function to fill in the model. Both can have headache-inducing issues.
Here is a PDF that shows how ANSYS SpaceClaim uses a different approach which can make the fluid volume extraction much easier for engineers:
