How to enter in Comsol5.4 a function containing an indefinite integral ?

Please login with a confirmed email address before reporting spam

Hello, I would like to enter in Comsol5.4 a function containing an antiderivative to represent the laser at any Z absorption depth (the specific formula is shown in the attached figure). I'm going to use this function formula as the coefficient of the equation I'm going to solve. How do I edit this function in Comsol?

I have tried to edit with component coupling (intop1 ()), but it seems that in the one-dimensional case what I got was not a laser in a specific position.
