I'm having trouble starting the simulation for my duct

hello, i am trying to simulate the duct design

( link : https://www.simscale.com/workbench/ ?pid=5276412059851307017 Aab012f58-15fe-4daf-bcff-bce04f9c8771%2Cservice%3ASIMULATION%2Cstrategy%3A7&ps=analysis%2FboundaryConditions%2F1 )

but i cannot as it is throwing an " Multiple boundary condition assignments for the following entities: face1927@solid1 ". how do I resolve this? what to I need to do more?


Hello 4bhagat,

from what i can see you have assigned the face 1927 to the velocity inlet as well as the velocity outlet. Please make sure that that face is only assigned to one of them.

The second error just says to you that you have top inlet definitions but no outlet definitions. This will mean that air will just be able to enter the domain but no exit. Please make sure that you have at least one inlet and one outlet defined for your simulation.

let us know if this helped you.

Best regards
