Hello friends,
I would really appreciate some help in defining a constraint. I am trying to solve a system of PDEs but the result at the earlier times keep overshooting the expected value. The maximum value for this variable should be 825, which is the initial value of this variable. However, each time I solve the system, I keep having the values of this variable within the first few seconds overshoot the initial value which is very unreasonable. This is a consumption problem, the values of the variable should be steadily decrasing to zero. Could someone help me out?
My objective is to constrain my variable to 825 each time the result obtained by solving the system of PDEs by comsol exceeds 825 but keep all values of solution less than 825 at t>0. Thanks for helping out.
