I'm new to Comsol and have some problem.
I have a room with 2 Inlets, on oen inlet air enters and on other there is hydrogen
The two gases mix in the room and there is one outlet
Required results:
Concentration of the hydrogen gas within the room
The mixing should be approachable by convection and diffusion.
my problem is to connect the certain gass with respective inlets
i define two material now how can i assign the hydrogen and air to their respective inlets
