Hi All,
In COMSOL surface tangential derivatives can be computed using dtang(V,x), where V : variable and x: direction.
Unfortunately, the help says a tangential derivative rule is only implemented for several variables.
Is there a workaround for the other variables ?
I need the vector of the tangential derivatives of the norm of the surface current density on a boundary in a 3D model.
Thank you very much for help .
