Grey is on a distinguished road
I want to simulate a model which has a negative pressure/suction at the common outlet and openings just like the one shown in the picture below. I want the wind to pass through the model, and the common outlet to have negative pressure(which means the system has to suck wind in). I made couple of trials by using fill command. But so far nothing worked yet. The First model without applying the negative pressure at the outlet performed successfully as I created an extruded part body as wind domain on the model surface on Design Modeler, and converted this part body and the surface body(the model which was imported from Rhino) into one part body by using Form New Part. But the obtained solution of the below model was incorrect. Refer the attachments for understanding which includes Rough representation of current model and Results from the first model. Kindly suggest me a best practice for this condition of my simulation.
