Changing bounds of mesh

[SA8416]

Hi

Is it possible to change the bounds of a mesh? For instance in: m = createMeshCylindrical2D(Nr, Nz, Lr, Lz)

Setting the values for Lr and Lz cause the mesh to extend from "0 to Lr" and "0 to Lz". Is it possible to change this so that the mesh extends from, say, "x to Lr" and "y to Lz" ? Thanks in advance!

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.
