I am using time-dependent solver for electrolysis process. Now I want to simulate it for 300 Secs. But in following manner ( i have written in syntax as we use in time stepping );
first : range(0, 0.0001, 0.001)
then in continuation second range(0.001, 0.001, 0.01),
then in continuation third range (0.01, 0.1, 10),
then in continuation forth range(10, 10, 300)
please advise me

Hi
what about trying something like:
{ range(0, 0.0001, 0.001) range(0.002, 0.001, 0.01) range(0.02, 0.1, 10) range(20, 10, 300) }
this should work, you must ensure the set is strictly increasing or decreasing

Good luck

Dear Ivar,
I have a very similar, related question.
I also would like to have this explicit time step range. And in addition, I would like to repeat the sequence for a given amount of times, say n=3 times.
{0}
0*300 + { range(0.0001, 0.0001, 0.001) range(0.002, 0.001, 0.01) range(0.02, 0.1, 10) range(20, 10, 300) }
1*300 + { range(0.0001, 0.0001, 0.001) range(0.002, 0.001, 0.01) range(0.02, 0.1, 10) range(20, 10, 300) }
2*300 + { range(0.0001, 0.0001, 0.001) range(0.002, 0.001, 0.01) range(0.02, 0.1, 10) range(20, 10, 300) }
something like the above. But then that also Comsol understands it.
Can you advise me on how to program this?
Many thanks in advance
