Reason

With the new Eigenvalue executioner, the only way to output the converged eigenvalue is to use a vector processor, which outputs all the eigenvalues that SLEPc calculated. In reactor physics, the only eigenvalue that really matters is the smallest one, so looking through csv files to find a single eigenvalue is a bit of a hassle. I would be nice to add the eigenvalue to the screen output and within the csv file with all the other postprocessor values.

Design

Create a postprocessor where users can define which eigenvalue they want to output, with possible tags:

  • Largest/smallest magnitude
  • Largest/smallest real
  • Largest/smallest imaginary

Impact

New output capability for eigenvalue problems using SLEPc executioner.
