Node ID mapping when reading ABAQUS mesh

[yw5aj]

Hi all,

I noticed that when I read in an ABAQUS mesh, the node mapping wasn't a simple +1 offset (as I imagined from

libmesh/src/mesh/abaqus_io.C

Line 532 in fd900b5

_abaqus_to_libmesh_node_mapping[abaqus_node_id] = libmesh_node_id;

). I am trying to read some nodal attributes from my code and therefore would need a mapping from the ABAQUS nodal ID to the libmesh nodal ID. Could you help share a pointer? I can share an example below too which will illustrate the case. Thank you!

Does the Abaqus file have its nodes written non-contiguously? Have you left mesh renumbering enabled on a DistributedMesh? Those are the only things I can think of that would give you unexpected numberings.

Renumbering! After doing mesh.allow_renumbering(false); it was all fixed. Sorry about the stupid mistake and thanks for the pointer!
