Hi everyone,
I am experiencing a persistent issue when trying to load LS-DYNA results in ParaView. Every time I select the base d3plot file and use the LSDynaReader, the following errors appear in the Output Messages:
ERROR: In vtkLSDynaReader.cxx: Database has bad state size (0).
ERROR: In vtkLSDynaReader.cxx: No valid time steps in the LS-Dyna database.
Unknown Dimensionality 0 encountered.
My environment:
ParaView versions: Tested on both 5.13.0 and 6.1.0-RC1 (Windows 10/11).
Data type: LS-DYNA simulation using SPH particles, written in Double Precision (DP).
Validation: The files open and animate perfectly in LS-PrePost, so the database is healthy and complete.
I have already tried to:
Shorten the file path to avoid Windows character limits.
Open only the base d3plot file (not the numbered ones).
Check both the stable and the latest RC versions of ParaView.
I found a similar discussion from December 2025 regarding crashes with discrete/eroded elements. It seems that when the simulation involves SPH or elements changing state, the reader fails to correctly map the memory offsets, especially in Double Precision.
Is there a specific setting in the advanced properties of the reader that I should use? Or is this a known bug with the DP reader for SPH data?
Thank you for your help!
