I'm having some difficulty in controlling the time step for results in a simulation I'm doing.

I'm trying to model a square tube being axially crushed by an impact load, and while the results I have match experimental results fairly well, I need finer time steps between results. I'm getting these results from "Tabular Data" under each solution. The end time for the analysis is 40ms, and the tabular data only shows data for every 2ms, despite my best efforts to change this. I've tried changing time history output controls and mesh size (global and specific body sizing) but these only change the time steps in the "Solver Output", and don't actually show me more detail in the individual results' tables.

Am I missing a better way of exporting this that might show smaller jumps between each data point, or will Tabular Data show me all the detail (if I configure things correctly)?

I'm on Ansys 2025 R2, on the Teaching license.

Hello User,

I will let someone else comment on the workbench table part, but if you're open to running this file in LS-PrePost, under *DATABASE_ASCII card, you can increase the output frequency. And once you have the results, when viewing D3plot file, you can view time history plots. You can also save these plots as csv file.

Regards,

Nanda.

Hi Nanda,

Thanks for your response. I'd ideally like to get my results through Workbench but I'll give LS-PrePost a try soon.

Kind regards,

Oli

If anyone else is struggling with this, following the trackers here - Force reaction in LS-Dyna workbench - sorted this out. It has limitations, but the two most important quantities I needed fine results for were force and deformation.
