Is there any way of saving convergence plots like step reciprocal against step number so that whenever a model file is opened, they can be seen?

Hi,

This is already possible using the following steps:

  1. In the Progress window, click the Copy Convergence Data to Model button (the leftmost button in the window's toolbar).
  2. In the Table window that opens (called Solution 1/Time-Dependent Solver 1, for example), click the Table Graph button in the window's toolbar to create a plot of the reciprocal step size.
  3. You would typically use a logarithmic y-axis in this plot to make it look similar to the plot in the Convergence Plot window.

This plot will be saved and opened with the model.

Best regards,

Magnus

In the Table window that opens (called **Solution 1/Time-Dependent Solver 1**, for example), click the **Table Graph** button in the window's toolbar to create a plot of the reciprocal step size. 3. You would typically use a logarithmic *y*-axis in this plot to make it look similar to the plot in the **Convergence Plot** window. This plot will be saved and opened with the model.

Hi Magnus, thanks a lot. But if these plots can't be saved automatically by clicking a button in the settings, it's a bit inconvenient as one needs to do this manually for every simulation run?

Could you record a method of the compute stage followed by the process Magnus describes?

Actually, just tried that and the generated code explicitly lists all of the data to be added to the new Table, so that won't work.... in which case, I agree, having a checkbox to automate this process within Comsol would be much better, (perhaps the table name could be linked to the internal ID of the version within the new Comsol Model Manager to provde traceability?)
