Intermediate step during a time step
I have a question concerning the managment of time information during a time step. I have the following situation:
During one time step from time t_k to time t_k + delta_T,
a volScalarField called myfield changes its value according to a partial differential equation PDE1. That's done by using
So now I have the volScalarField myfield at time t_k + delta_T. Now I want to solve to steady state another pde PDE2 for myfield, starting from the myfield at time t_k + delta_T. The steady state solution of PDE2 for myfield should then be used as starting value for the next time step from time t_k + delta_T to time t_k + 2*delta_T using PDE1.
Has anyone done something similar or an idea on how to do it? I have tried using subCyclceTime and subCycle, but without success.
