Determine fluid volume of a design

Use Fluid Volume to create a component that represents the internal or external volume of a design.

Use Fluid Volume on models that are typically used for CFD analysis.

The internal volume is a solid that matches the interior shape of the model. The model faces are copied to create the solid. Therefore, any openings result in a surface with missing faces. Cover (cap) the openings with a surface before you create the internal volume.

The external volume is a box, cylinder, or hemisphere with a void created by subtracting the model. If the fluid flow is only outside the model, cover any openings. Openings in the model result in the void with both the interior and exterior shape.
