ExodusOptimizationSteady

Object for output data in the Exodus format

Overview

This Exodus output object has the features of Exodus and allows for SteadyAndAdjoint and Steady solves to output a per-iteration output. This allows users to analyze the evolution of the optimization process solution as it converges to optimal values.

A test example is listed below:

[Outputs]
  console = false
  [exodus]
    type = ExodusOptimizationSteady
    execute_on = 'TIMESTEP_END'
  []
