I'm trying to model the pre-stressed impact of a composite structure in Ansys Workbench LS-Dyna. I use ACP to model plies and transfer data to the LS-Dyna system to model the pre-stressed state of the structure. The 'History Variables' option of 'Output Control' is turned on and this data appeared in LS-Dyna results. The 'Stress File for the Flexible Parts' option is also turned on to make it possible to transfer stresses to subsequent analysis.

Then I transfer data to the LS-Dyna Restart system with the Full Restart setting in its Analysis Settings and 'History Variables' option of 'Output Control' turned on. The solution is completed successfully with pre-stress and impact sequential processes but the history variables aren't accessible! These items are in the Soution's worksheet but I get the error message: "An error occurred when the post-processor attempted to load a specific result. Please review all messages." (see Figure 2) when I try to obtain them!

Is there a way to overcome this issue?

Hi,

I see you reposted this query and a query is already open: History variables aren’t accessible in LS-Dyna Full Restart system in Workbench (ansys.com)

I will close this thread and keep the other one open.
