I looked in the documentation and couldn't find any information on how to do this:
m = m + 10
I would like to have accumulate some value to m for each time step.
Please share some light if you know.
m = m + 10
I would like to have accumulate some value to m for each time step.
Please share some light if you know.

Dear Minh,
You can use a Global ODE as a counter in some sort.
Attached you find this example where I defined an m, where the time derivative of m (mt) is equal to 10. In other words, every second, 10 is added to m.
Not exactly every timestep, but I assumed that this was meant.
Note that if you really want to add 10 every timestep, you might be able to rewrite the time derivative of m in a way that it is dependent on "timestep".
Best regards,
Frank

Dear Frank
I am working on lithium-ion battery module. In this model the current switches from positive to negative and vice-versa. I want to count the cycle number. Could you suggest me that how I can find the cycle number.
Thanks and regards

Dear Rashid,
I am in the same situation as you.
Did you finally manage to solve the problem?
I am modelling material removal. In each timestep there is a logic value (0 or 1) defining which elements should be eliminated. I would like accumulate these values in a counter variable, so that at the final time, the remaining elements have value 0 and the ones to eliminate >0.
Thank you in advance.
Best regards,
