Time Derivative Propagation is the method we are using for implementing the time-dependent random ray mode in OpenMC

Objectives

  • Be able to describe what Time Derivative Propagation is.

Guiding Questions

  1. What is the major computational drawback to a finite-difference approach to time stepping in the method of characteristics? How does Time Derivative Propagation address this issue?
  2. Why is time derivative propagation an ideal candidate for time dependent random ray? What gaps does it fill against other approaches?
