failed to evaluate variables

Hi ,
I am building a 3d model of fluid flowing around a wafer using 4.3a. The following error occured when I tried to plot the pressure on the edge of the wafer.
Cannot ecaluate expression.
Failed to evaluate variable.
- Variable: mod1.p
- Geometry: 1
- Domain: 5
Failed to evaluate expression.
- Expression: mod1. p
- plot: lngr3(line graph)
Domain 5 is the wafer in my geometry. Can anybody help me out please?

Hi
"p" is the pressure, if its a dependent variable it sould be called as "p". Now you might have played with the physics when defining the model, such that COMSOL has called the pressure p2 or p3 (in cae of several "p's" then you should check the name of the dependent variables (main physics nodes - dependent variable tab adn then compare with the one of the plot call

Good luck
