Hello,
I'm very new to Comsol and I have several questions.
1.Since I'm more proficient in Matlab is there anyway to use Comsol solvers through Matlab?
2.I need to solve a homogeneous wave equation:
d^2E(x)/dx^2+w^2*eps(x)*mau(x)*E(x)=0
At first to get a hold of things I tried to solve it eps and mau as constants,but when I take boundary conditions of zero at both ends I just get a straight line instead of a sinusoidal wave.
What boundary conditions should I use?
3.When I get the results I see one line but if the answer is complex how can I choose to see the real/imag/abs of the solution?
4.Is there a script base Comsol interface?
Thanks in advance.

Follow up question, can I solve the wave equation with only one boundary conditions and let the other boundary be resolved by the solver?
