COMSOL: Setting up simple optimization problem

Hi all, i have some doubts about setting the COMSOL optimization module.

My aim is quite simple, i should find the optimal value of a variable to minimize the objective equation.
In particular i should set up the parameter C in this equation(which represents the outlet pressure of a laminar flow model):


in order to minimize the following equation:


Where p is the pressure coming out from linear flow model (spf) and 15000 is a reference pressure, both applied to domain.
The algorithm is quite simple, comsol should:

1)assign a value to C
2)estimate the value of domain pressure( coming out from laminar flow model)
3)verify if optimality condition is satisfied, otherwise start again from 1

My doubt is about implementation: which kind of objective should i use (integral objective, probe objective...)? Should i use inequality constraints too?

Best regards
