Hi,
I want to break my simulation into different time time intervals, can it be done in comsol?
For example,
my time interval for the simulation is (0,20,100)
can I run the same simulation for (0,10,40) continued by (40,20,100)?
something like this.

yes, you can.

in study section: for defining time Interval just add the time that you want.
check the screenshot that I put it here.

Hope it helps.

Note that both time interval options you mentioned request a solution from time 0 to 100. The steps you specify between 0 and 100 do not directly affect the step size taken by COMSOL (they may be bigger or smaller depending on the model). Instead the specified steps determine the times at which results will be stored. If you want to ensure that the solver will not skip over the selected times you should also set “Steps taken by solver” to “Intermediate” or “Strict” to prevent COMSOL from potentially taking too big time steps. That setting is in the Time Stepping section of the Time-Dependent Solver node.
