How can I define an arbitrary function as an initial condition?

Hi!

I am new to COMSOL, and I am trying to solve the diffusion equation by PDE interface module.

For the initial condition of the diffusion,

I want to define square concentration of amplitude 1 which ranges from x=44 to 84 within total range (0 128)

How can I define this function and use it as the initial condition?

Thank you for your attention!

This problem has been discussed in this forum quite frequently. Type, e.g. "pulse train" in the search field.
