Hi everyone,
I am a new user of this software. I heard this is a very powerful software but I really don't know how to use it. Hope someone here can help me out.
The problem I try to solve is I have a sealed disk-shape cavity. The cavity is filled with air initially(N2:O2=4:1). I open a hole at one end of the disk to inject pure N2 then open another hole at the other side of the cavity to expell gases. It is expected the O2 concentration inside the cavity should decrease with time. I want to know the O2 concentration distribution inside the cavity at any moment.
Can someone help me out?
Thanks.

Hi
The quickest way to learn the tool is to go through several of the examples in the doc and from the model library, take the simple one to start with one physics at the time, select the ones that uses the physics you believe you need for your example. Then only start with your own complex example.

Good luck
