mfem.gridfunction.getAllNodalValues

Gets the values of a grid function at all vertices of the mesh.

Syntax

mfem.gridfunction.getAllNodalValues(gf, vdim?)

Description

Gets the values of a grid function at all vertices of the mesh. This returns one value per vertex for the entire mesh, which is useful for visualization or post-processing. For vector-valued grid functions, you can specify which component to extract.

Parameters

NameDescription
gf- The grid function to evaluate
vdim(optional)- Vector component to extract (1-based, default 1 for scalar)

Returns

Float64Array
