I use the 'non-isothermal flow' module in COMSOL 4.4
I am trying to understand how COMSOL exacly solves the NS equations..I know the equations used (mentioned in the user's guide)..
There are ample references in literature for how NS equations are discretised in finite volume methods ( streamline vorticity formulation,Primitive variables based method etc).
I could not find any similar references for finite element approaches.
Any help will be appreciated.
