Changing Time stops

Hello, I am in the middle of a simulation tha seems to be taking ages, can I stop and change the the total time ? or am i stuck

From the solver manager, you can edit a run in progress (edit button toward the right end of the button row). This fires up the CCL editor for the running job. Change the stop conditions and save the file, exiting the CCL editor.

This works well if it's a steady-state run. Unfortunately, if it's a transient run, I haven't had much luck changing the time steps, total time, or other transient parameters.

Use "cfx5stop -dir yourrun.dir" in the command line. See manual for instruction.

Hi,

That command will stop the solver at the end of the present time step. But imagine that you set the simulation Total Time to 30 s and you want to change it to 20 s. Edit Run in Progress seems to not work in transient simulations, so is there any way to change the Total Time ?

Thanks and regards,

Rui
