How to Perform a Parameter Estimation Study in COMSOL®

[@kristianjensen8976]

COMSOL 5.3a does not support transient control variables, but you can define a function f(t) = a0+a1*t+a2*t^2 etc. with an arbitrary number of parameters a0, a1, a2. You will then be able to solve the least squares optimization problem with respect to those parameters.

extremely useful, thank you!

Is it possible to estimate transient value of parameter, which changes with time? If yes, then how?

I have same question I really need answer if you knew it
