Steady state dynamic linear elastic (Helmholtz type PDE)

Asked by Bahram

Hello,
I am very new to FEnics, I want to solve the steady state dynamic linear elastic model in solid. my equation is function of frequency and the strong form is:
Divergence(stress(vec(x), w)) + w^2 * density * u( vec(x),w)=0
BC: Stress(vec(x),w) n(x)=T(x,w)
u(x,w)=U0
I already wrote the weak form but since I couldn't find any example or demo similar to what I want to do . does any one can help me how should i deal with this problem and solve the problem in a range of frequency or give me some tips about this problem.

Thanks
