Hi, I am transferring fenics to dolfinx but having a trouble now. I was wondering how can I get the array of vertex values coinciding with the nodal order like compute_vertex_values() in fenics? The reason why I need this function is to verify my solutions. Thanks for your help!

Compute point values does the same thing as compute vertex values for a first order nesh. For a second order mesh it computes the values at every node on the mesh geometry. If your mesh is first order, it should return you the values at each vertex.

How to get vertex values in dolfinx?

From the change log of the dolfinx-tutorial,

dolfinx.fem.Function.compute_point_values has been deprecated. Interpolation into a CG-1 is now the way of getting vertex values.
