I am curious if it is possible to plot differences in certain variables between, for instance, location a and b. An example, I have a temperature distribution between x=0 and x=1. I am interested in the temperature difference between x=0.2 and x=0.8. So I want to plot T(x=0.8)-T(x=0.2). Is this possible? |

The VAL(expression,xpoint,ypoint) function returns the value of its argument expression at the stated position in the mesh. The EVAL() function does the same thing, with different characteristics of integration into the solution method (See VAL in the Help Index). Either one can be used to plot the information you want, as in HISTORY(VAL(T,0.8)-VAL(T,0.2))
