Title: Freezing FE Iteration at specific candidate
Post by: JanPio on April 16, 2018, 08:03:18 AM
Hello,
we currently use HyperSizer 7.3.50 with ANSYS 18.2 in order to find the most promising design of various design concepts for a metallic fuselage-wing-connection. Our data structure is as follows:
Problem: The iteration process with HyperFEA works in general, but we recently experienced some freezing FE iteration processes. Details:
Workaround: Compacting the database sometimes helped repairing the files and those iterations finished successfully afterwards, but some still have the problem. We observed that changing step sizes in the Sizing Form helped: it did not get stuck anymore.
Question: What is the root of the stuck processes and how to solve it? Is HS encountering memory problems, maybe because of the many projects in the database?

Thank you in advance,
Jan

For all who have similar problems, ours is solved: we used the FEA loads extraction method "element based" (can be changed in the Sizing Form --> FEA Loads). Changing it to "peak element filtered" made the iteration process finish successfully. Apparently this specific component was overchallenged with calculating every single element.
Thanks again Brent.
