I want to solve a set of coupled equations using weak form of Comsol. Some tuitials are available for solve simple uncoupled equations using weak form in comsol, which doesn't seem to work for my case.
The equations may look like this (just a simplified form for an example),
r^2*(d^2T/dr^2)+3*r*(dT/dr)+Eh/2*(dw/dr)^2=0
B*(d^2/dr^2+1/r*d/dr)^2w-T*(d^2w/dr^2)-1/r*(dw/dr)*d/dr(r*T)=p
Note: I am aware that the ODEs above may be solve by some other special Modules, but they are just a basic example. I am trying to learn how to solve coupled equations using weak form Module, so that I can solve more complicated equations.
Any suggestions would be appreciated.
