EigenValueDynamic

Represents the eigen value dynamic analysis. Only nroot smallest eigenvalues and corresponding eigenvectors will be computed. Relative convergence criteria is governed using rtolv parameter. Nonzero value of optional parameter renumber turns on the equation renumbering to optimize the profile of characteristic matrix (uses Sloan algorithm). By default, profile optimization is not performed. It will not work in parallel mode.

The eigensolverparams parameter describes the sparse linear solver attributes and is explained in section 6.18. Can be used in parallel mode. The input record must be the same for all processors. Parallel version requires PETSc and SLEPc modules.
