Hi,
I think you need to set both which eigen pair and the target value. For
example, if you look for the eigenvalue closest in magnitude to 0, you need
to set the following
const double target_eigenvalue = 0;
eigensolver.set_which_eigenpairs(EPS_TARGET_MAGNITUDE);
eigensolver.set_target_eigenva
Dear All,
I am trying to use a shift-invert transformation in step-36. I did minimal
changes in the solve function adding the following code that describes what
spectral transformation I need to do:
SolverControl solver_control (dof_handler.n_dofs(), 1e-9);
SLEPcWrappers::SolverKrylovSchur eige
This issue is now fixed by a PR merged yesterday.
