and why is the 1st solution I mentioned not ok?

Just load your 15th timestep or choose from the (clock) tipe of buton on top in post

My requirement needs a force from expression.

I am using this expression in optimisation problem as the output parameter to design of experiments (DOE). This DOE takes the values of the first time step, which not a desirable for my problem. Instead, i want maximum value of force among all time steps (nearly 250 are there in my analysis).
To obtain this I have to write an expression which could calculate the force at a particular time (time belong to max value of force) then i can assign this expression as the output parameter to DOE.

Now this is quite a diferent thing than originaly posted.
i think this will be a tough nut to crack.

I am thinking something about; if and acumulated timestep but i doubt that this will work in this case,

Yea, I am trying all possible ways but it still taking the default time. If could manage to calculate the force though CEL with a current time step, it would solve my problem. Since I know which time have maximum value of Force.

Thank you.
