Changing bounds of mesh about fvtool

[SA8416]

And to add, is there a way to extract the gradients of a distribution along with the distribution itself?

Hi @SA8416
It is possible to shift the origin:

m = createMeshCylindrical2D(Nr, Nz, Lr, Lz);
m.cellcenters.x=m.cellcenters.x+x0
m.facecenters.x=m.facecenters.x+x0
m.cellcenters.y=m.cellcenters.y+y0
m.facecenters.y=m.facecenters.y+y0

It is a bit cumbersome and ugly. I'll add a function to do it automatically.

I don't quite understand the second question. Do you want to get the gradient of a cell value? You can always use gradientTerm and gradientCellTerm functions.

Thank you for the swift reply! I'd like to get the gradient at each face of a cell (north south east and west for 2D), including cells at the domain's boundaries.

Then you should use gradientTerm function.
