Hi all,
I hope everything's well for you ! I am fairly new to COMSOL and I am performing a CFD simulation with laminar flow and biphasic flow with level set method. As I am studying the filling of my geometry, I use a time dependant study.
I am facing an issue with the simulation : - I assigned a first step of initial value in my first domain with my material that will fill the cavity (u = 3mm/s et a pressure at 1) - I assigned a second step of initial value for the air present in the cavity where nothing happens at time t=0s (everything is at 0)
However in my results, it seems that only the initial values of my first domain are taken into account in all the geometry, and I cannot really understand why. Has anybody faced the same issue and can maybe give me some advice on this ?
I hope I have been clear enough ! Here are some photos of my geometry : - The first one shows the speed at time t=0s where I think I should see no speed in he second domain - The second one is to show the two domain I am working with Thanks in advance for your help !
