Description of the bug
I have a LS-Dyna simulation with adaptive mesh refinement that I would like to post process the results (last state only) using pyDPF. DPF is able to read the changing mesh at the last step, but the displacement field is empty with 0 entity:
However, I found that if I simply delete the d3plot files for all states except for the first and last states (the ones highlighted here):
then the same script works, it reads the last mesh and the displacement field is not empty. Both the mesh and the displacement field match with what's observed in LS PrePost:
However, other result operators (like the dpf.operators.result.thickness and dpf.operators.result.total_strain in the provided example) work fine even when all states are present in the d3plot files. The example can be found here:

- Run the script with all d3plot states present
- Delete the highlighted d3plot files
- Re-run the script
