Pseudo Time Stepping
In order to improve the solution robustness, pseudo time stepping can be used for the Curing Reaction interface when solving a stationary model. Using pseudo time stepping, a fictitious time derivative term:
is added to the left-hand side of the curing reaction equation. Here
is the pseudo time step. Since
is always zero, this term does not affect the final solution. It does, however, affect the discrete equation system and effectively transforms a nonlinear iteration into a time step of size
