I am trying to follow the steps written in Dr. Voelker's thesis(digbib.ubka.uni-karlsruhe.de/volltexte/documents/1621606). I understood the weak expression and its COMSOL form, but i am facing a problem in specifying the parameters and variables.
I am not getting the idea how shall i define Px, Py, Pz , phi and do i need to define ux, uy uz or comsol will automatically take care of it as i have defined it as the dependent variable ? I am using comsol 4.3a and i am not able to include the boundary conditions(point settings and boundary settings) as mentioned in the thesis. I am a new user of this software and donot have much idea about this.
Can you please help me or give me any suggestion regarding this problem if possible ?

Thanks
Soumya
