Hi, I am trying to simulate the direction of the liquid crystal molecules inside a capacitor. To do that I need to solve the following PDEs.
(1)
Where V is voltage across the capacitor.
(2)
Where theta is the angle of the liquid crystal molecules and Ez is the strength of the electric field on the Z direction
(3)
(4)
To solve (1) I was thinking to use the electrostatic module, and for (2), I was thinking of using the coefficient form PDE module. However, for some reason I am not able to couple them inside comsol Is this possible to solve in comsol?
