Hi, Dave! Thank you for your assistance. The problem is that I don't have the matrix representation for my problem. I've searched on the internet for a solution, but found only some examples of solving 2D eigenvalue problems for the Stokes equations. Maybe you could help me with the matrix representation for the 3D Stokes eigenvalue problem?
Thank you in advance,
Alex

I would like to use SLEPc iterative solver for this purpose, but I'm not quite sure how I should set up the matrices for the solver. I would be grateful if anyone could share a source code for solving this eigenvalue problem.I presume your forward model uses petsc. What matrix representation do you use in that code? Why cannot they be used directly with slepc?ThanksDaveThank you very much!Alex
