Hello ALL,
I am trying to build an axisymmetric model with acoustic-shell interaction multi-physics. Acoustic- shell interaction is under 3D geometry. So I have to creat a 3D geometry which is using cartesian coordinate. In my model, i need to apply a dipole source in domain. But my dipole source expression is using cylindrical coordinate. I have already define an cylindrical coordinate in comsol, but i can not choose coordinate system in dipole source setting. Is there any way i can apply cylindrical expression for this dipole source?
Regards,
Margret
