Hi,

I am a new to COMSOL and I want to load the air to one subdomain but I have some problem. In 3.5a when I load air to the subdomain, how can I define the density and the dynamic viscosity of air? I tried to give the P and T but it doesn't work. What should I do?

Thank you for the help!

Hui

Hi

I canjot fully remember how it was (getting old 3.5 and myself ;) but if p and T are not defined by the physics, you MUST define them as Constants / parameters

Good luck
