Help with my model

these are my models, its supposed to go from the left to the right, however it keep repeating the same error message over and over again.
Additional info, the bottom of the cone is blocked out and there are only 2 holes for water to go into and out of, help will be appreciated.

Hi there!

Thanks for sharing the images and details of your model. The Internal Flow Volume extraction is failing because of how the Seed and Boundary faces are assigned.

To extract an internal flow region successfully, the algorithm needs to know exactly where the fluid is and where it stops:

  1. Seed Face: This acts as a starting point inside the fluid domain. It must be an internal face that touches only the fluid region.

  2. Boundary Faces: These are solely meant to “cap” the physical openings of your model so the extracted fluid volume doesn’t leak out. You currently have the internal splash board selected as a boundary face, which is contradictory and breaks the operation.

How to fix it:

  • Remove the splash board from your Boundary faces selection.

  • Keep the inlet and outlet opening faces as your Boundary faces.

  • Crucially: I noticed two small square cutouts/holes on the upper wall of your main cylinder. If these are open to the fluid domain, you must create caps for them and select those capping faces as additional Boundary faces.

Let us know if this resolves the error!

Cheers,

Igor
