THMSolvePostprocessorControl

This component controls the solve based on a postprocessor value. If the postprocessor indicates zero, no solve is being done. Otherwise, the solve is performed.

Example input syntax

In this example, the problem is only solved between time 0.4 and 0.6s, when the value of the postprocessor in non-zero.
