Stop simulation based on residual using python/batch script

Post by Jimmy Azarnoosh » Wed Apr 05, 2023 2:59 pm

Hello,

The simulation stops in Simvascular using a specified number of timesteps. I'm doing steady simulations and want to stop the simulation based on a specified residual, i.e. stop calculation at residual less than 1e-6. How can we do this using Python or batch script?

Thanks,
Jimmy

Hi Jimmy,

The third column in the histor.dat file contains the nonlinear residual.

The easiest thing to do would be to write a bash script to launch a svsolver job and then check the value of the residual from the last line in histor.dat. If the residual is smaller than a tolerance then kill the svsolver job.

Cheers,
Dave
