Can I Continue an Existing Simulation Run in SimScale?

In some analysis types, it is possible to continue an existing simulation run. This feature is called ‘Continue the run‘ and it is useful when your existing simulation has not converged or if you want to extend the simulation run without changing the simulation settings. This feature is active for steady state simulations.

Below is the list of all the analysis types which support the Continue the run feature:

• Incompressible
• Compressible
• Convective Heat Transfer
• Conjugate Heat Transfer
• Conjugate Heat Transfer v2.0

To be able to continue an existing steady state run, first click on the Run and click on the ‘>>’ icon referred to as ‘Continue the run icon’ beside the post-processing results button:

Next, define the End time and/or Maximum runtime. In a steady state simulation, end time stands for the number of iterations, while maximum runtime is the maximum allowed physical time for the extended run.

• If the simulation ended before reaching the original end time, it is possibly because the assigned maximum run time was not enough. In this case, just increase the Maximum runtime.
• If the simulation has reached the defined end time and you would like to perform additional iterations, then increase the End time. In addition, you will need to check the duration of the simulation job for the existing number of iterations. This will give you an idea regarding the suitable run time for the job. Finally, increase the Maximum runtime if necessary.
