Hi!
Please, anyone, help me!!!! I'm totally new to Comsol, but my task is to model the flow of air in a chamber of the mass spectrometer connected to the second chamber through the small orifice. There is an inlet of air into the chamber through another small orifice at the opposite wall (i.e., the inlet and the outlet, in terms of boundary conditions). A vacuum pump is attached to one of the chamber walls, and it pumps the air at a constant speed (0.067[m^3/s] ). The chamber walls are made of aluminium. The temperature I guess should be constant. I'm interested in pressure distribution inside of the chamber and the air flux. The pressure in the chamber is 2 mbar (which is below the atmospheric pressure), and hence the flow is in a slip flow regime with 0.01
I think your not specified properly the variable component i.e. may be a temperature, specify the correct value of the temperature and In the geometry one of the domain not selected properly.
Thank you, Dr. Krishna! In which place I should place this temperature variable inside (apparently, it applies to physics )? Does it have anything to do with the Heat transfer module?
I am unable to open ur file because i am using comsol 5.2. Can u send me the file after saving with lower version so that i will try to help u.
There is no way to save as an earlier version, except .java file, which you can then compile to your COMSOL version, as described in the link below

Maybe I've attached the wrong version of my model. I still can't find the way to define the temperature. Thank you for helping me, Dr. Krishna!
