Hi,
I am an expert in Comsol, especially in heat transfer and fluid flow as they are parts of my PhD thesis.
I need to know the version of comsol you are working on.
Does the project related to your study (education) or industrial project?
And it seems your model need to be performed in 3D simulation, I suppose you have a strong enough computer.
About teaching and communication, it's not a problem to me.
