<p>Hello all,<br><br>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 (see first workflow row in Figure 1). 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.<\/p><p>\"\"<\/p><p>figure 1 – Workflows to get pre-stressed impact of composite structure with history variables<\/p><p>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!<\/p><p>\"\"<\/p><p>Figure 2 – Error message during history variables evaluation in LS-Dyna Restart system<\/p><div class=”v1pre”>There are no relevant extra messages on this matter in UI!<\/div><div class=”v1pre”> <\/div><div class=”v1pre”>The second workflow (see second workflow row in Figure 1) was created using dynain file to avoid the use of Full Restart.
