I am using COMSOL 5.0. I am working on modeling two phase Darcy's law, but when I run time dependent model, it shows me the error "Time derivative only allowed with respect to mesh time". I don't know what is the reason for this error.

Google forum suggests to change d(p,t) to d(p,TIME), but I don't know how to make these changes. Please let me know.
