Hey, i want to plot the derivation of the temperature and time (dT/dt) at a specific point over the time. If I enter the expression "d(T,t)" I get the error "Time derivative only allowed with respect to mesh time". If I enter the expression "d(T,TIME)" I get were odd results that cant be true. Can someone tell me the right expression for my problem?

Carl,

d(T, TIME) is correct. Derivatives can be noisy.

Cheers Edgar
