or

so use it in the place of "y" in your equation. Basically "mesh.C()" is a vector field of cell center coordinates. I'm sure after this it's easier to look for more examples.

what if I want to use command mesh.C() in other source files? I tried it but the compiler keeps telling me that I have to declare mesh first. So how am I gonna access mesh in other source file and declare it?
