I am trying to give an user defined function for viscosity which is a function of pressure and shear rate. I want to take the value of pressure to be the pressure calculated by comsol but then i do not want that pressure value below a certain limit so i want to give the minimum value of p for it. Is there any way i can do it in comsol5.1?

You can just write it for example if you dont want it to be below x you can write min(x,function) comsol recognizes it like that
