Hello all,

I am trying to load LS-DYNA D3PLOT files from Arbitrary Lagrangian-Eulerian (ALE) and Structured Arbitrary Lagrangian-Eulerian (S-ALE) simulations into VTK data structures. However, it seems that the LSDynaReader often fails on the D3PLOT files output from these simulations. As an example, a recent simulation produced the initial D3PLOT file (named exactly `d3plot`) and a series of D3PLOT files afterwards (following naming convention `d3plotXX`). The initial `d3plot` can be loaded, but trying to load any of the `d3plotXX` files results in the following error:

Any guidance would be much appreciated. Thank you!

It seems that I cannot upload files, as I am a new user. I was able to replicate the behavior with the [Quadrature C](https://lsdyna.ansys.com/quadrature-c) example from the LS-DYNA website, which runs in a few seconds. The main `d3plot` file can be loaded fine (and in ParaView seems to support playback), but the individual `d3plotXX` files cannot be loaded. It seems that LS-PrePost cannot load the individual `d3plotXX` files either.

Perhaps this is a case of user error, as the `d3plotXX` files may only be valid as a series (and not in isolation)?

Now you can 🙂
