I am currently simulating the effects of thermal stress on an underground power cable and I was wondering if anyone would know how I could set the time of the study to be over months/years instead of seconds/minutes? As I want to see the effects over some months/years.

Thanks

Hi, you can just set really long times in the time-dependent study, like range(0,6[h],10[d]) will simulate for 10 days in 6 hour intervals, or range(0,10[d],5[y]) will simulate 5 years in 10 day intervals. 1[d] is equal to 86400[s] and 1[a] is equal to 31556952[s]. Please note that a month is not a scientifically accurate unit and is therefore not used in COMSOL.

You can also set the unit at the top of your time-dependent study to "d" or "a" and then just write range(0,1,20) in the text field and it will append the selected unit to those.
