I am working on simulating the airflow in a cooling duct for a 3D printer. My first few simulations went well, but I am now having problems where it does not allow my to start a Simulation run, with the error:
Assignment on defeatured entities solid_0_face_68, solid_0_face_74 not supported.
This was from the Simulation setup: https://www.simscale.com/workbench/?pid=2417894775922761643&mi=spec%3Ab98650d4-3654-497b-bfa0-c69f11d05df4%2Cservice%3ASIMULATION%2Cstrategy%3A4
An earlier run, with a similar surface, generated by the same original code, worked quite well:
The surfaces that it is complaining about are the air intake faces, which I am assignming as velocity inlets/
What does it mean by defeatured surface, and why does it not like these faces now, when almost identical earlier versions worked fine?
