Hello everyone,

In the COMSOL v5.1 doc i haven't found the mathematical description on how does the automatic geometry analysis or the curvilinear coordinates adaptive method works.

It would be convenient to have an idea about how does the Ecoil vector field is derived in a mathematical sense, precisely for the research purposes.

What i have managed to find out is that there are weak expressions used by the name of cc.adap1.weak1 and cc.adap1.weak2 in the domain region and cc.adap1.inl1.weak1 at the inlet, and at the outlet the constrain cc.adap1.out1.constr is prescribed.

In most other physics interfaces weak expressions are shown in terms of the variables and the mathematical background could be understood.

Thank you in advance,

Edgaras
