I am new to COMSOL. I need to create a 2D model for back flow in Fiber Impregnation stage in a tapred die.

i have an equation for porosity which changes along the tapred region. I also have equation for pressure as a function of porosity.

Porosity= F(x) where x is length 0<x < L (L is total length of the die).

Pressure = F(porosity) 0<= x <= xin (xin is position of inlet along the die )

Pressure = G(porosity) xin<= x <= L

How to do you write pressure equation which has conditions above mentioned?

Thank you in Advance
