Postprocessors

The Postprocessor object is the pure-virtual base class for defining all Postprocessors in MOOSE. It defines a single method that all Postprocessors must override to produce a global scalar value. This method is generally called and stored in multiple Output formats once per time step (when applicable).

  /**
   * This will get called to actually grab the final value the postprocessor has calculated.
   */
  virtual PostprocessorValue getValue() = 0;
