I’m not experienced with the simscale software, so I’m not sure where I’m going wrong so I’m just going to explain my goals and what I’ve tried.
In this image is my model. My goal is to simulate a heater/fan blow in air from the raised blue square on the left, and then there to be outlets on the 0.25" raised portions around the model (the light blue on top, orange on the front face, circle on the left), while the other portions remain solid walls. I’ve tried running a simulation with the inside face of the square chosen as a velocity inlet and then all of the faces of the objects I want to outlets as velocity outlets, but my simulation fails. What should be the correct set up for this?
