Hi @mrodri61, thanks for posting
The link you’ve posted takes me to the dashboard - can you post your project’s link? You can get it by copying the browser’s URL inside the project.
In general lines, I’m not sure what you mean by “seed face” in the context of setting up the simulation. Usually the seed face is the face in contact with the internal volume when a user tries to generate an internal flow region.
Cheers
