We've identified an issue that occurs in Autodesk Simulation Moldflow Insight 2013 when using multi-threading for warp analyses on models over 1 million elements. This is not a guaranteed occurrance, as many models of this size will run just fine with multi-threading. But some do show this issue.
Outcome:
The issue creates obvious invalid results, typically exceeding 10's of thousands of millimeters in total deflection. Again, this is rare, and it doesn't invalidate any other results.
Workaround:
The work around is quite straight forward. You simply need to disable the multi-threading for warp analyses. This is done by opening the Process Settings and stepping to the Warp page. Here change the Number of threads for parallelization to Single thread (No Parallelization). If you already have results, when accepting the changes and selecting Finish in the Process Settings, only the warp results will be cleared so you won't need to rerun the entire analysis.
Moving Forward:
The source of the issue has been identified by our Development team. We're currently working on a hotfix to apply to the software to address the issue moving forward. In the mean time, continue using the software as normal. The situation occurs on a fairly rare basis, and it does not invalidate the accuracy of the results. Due to the obvious nature of the issue, should it occur simply reconfigure the warp to run with a single thread to address the issue. That will then provide the accurate warp results you expect.
Update:
This issue has been hotfixed for both Insight and Adviser. Each needs to be at Service Pack 2 level to apply the hotfix, those updates can be found on the Subscription Center. The hotfix can be found on the product support pages (Adviser and Insight) as well as the Subscription Center.
