Hello!

My question is how I can get current value of 'Reciprocal of step size' that convergence plot uses. The value normally plotted during calculation in COMSOL window, therefore I think may be the value can be get using some expression. If I know the expression, I'd like to use it for STOP condition. Thank you. Have a nice day.

Hi,

The current step size is available as a variable, timestep, which you can use in a step condition. The step condition can be any Boolean expression, so you could use something like

(1/stepsize) < 100

for example, if you want the time stepping to stop when the reciprocal step size drops below 100.

Best regards, Magnus Ringh, COMSOL
