How do we input a weak form including "vectorial" test function in COMSOL5.2?

05 May 2018 0 8K Report

Dear all,

Dose anyone know how to input the weak form of the equation attached as followed in COMSOL5.2? The equation contains three dimensional (3D) "vectorial" test function and vectors. We have no idea of solving this question since there are few information in the help or reference offered by COMSOL. Thanks anyone in advance for providing any helpful information.
