HI~ I am trying to implementation about GLS, SUPG stabilization method.
So, I got the information them in comsol.

'gls_ns','-test(nojac(rho)*(nojac(u)*ux+nojac(v)*uy)+px-nojac(eta)*(2*uxx+uyy+vxy))*taum_ns*(rho*(u*ux+v*uy)+px-Fx-eta*(2*uxx+uyy+vxy)),....
'taum_ns','nojac(1/max(2*rho*sqrt(emetric(u,v)),48*eta/h^2))'

i interpretation these code.
but i don't know meaning of emetric and why use nojac operator.
could i get these information?
thank you~
