How to run calculation from last time step?

#1 · July 15, 2026, 4:36 am

I am aware the run conditions can be updated while the calculation is running to increase the amount of iterations, but is it possible to have the solver start again after finishing without convergence yet? For example start from iteration 500?

If you click “Start Calculation” after the calculation has finished, the calculation will start from the last saved time.

There is no feature to resume the calculation from a specific time. This option is not available in the GUI, but in Expert Mode, you can run the calculation by manually editing the `startTime` value in the `system/controlDict` file.
