Suggestions & Feedback / Results deleted after renaming project
« Last post by JanPio on August 03, 2018, 06:18:41 AM »
Hi again,
I currently face this problem: I changed a material setting, just for a moment, so at the end the material had the same settings again, but I had saved it in between.
Now my sizings (HyperFEA Iteration results) are deleted are not available for reports anymore for all projects that used this material.
I can still click "Run ANSYS" and see the iteration graph, and I see results such as Unit Weight in the FEM-Viewer.
But I cannot create reports anymore and all the dimensions in the sizing tab are grey. The project folder that belongs to the project only contains an empty folder "FEM", nothing else is left.
(BTW, why do I still see results in the FEM-Viewer if the project folder is empty?)
Is it possible to get the reports back?

viewing-only should be enough in most of the cases, thanks!

Hi Jan,

One way to view the project is to open another instance of HyperSizer while the "Analyze/Size" process is running. However, we do not recommend doing this because any changes saved to the project during the "Analyze/Size" process can result in database errors.

Being diligent to only operate in a view only mode while the HyperSizer analysis process is running should not cause issues. What we mean by "view only mode" includes plotting dimensions, analysis results and reviewing sizing form inputs. Another important note is to close the second database before the "analyze/size" process is finished.

Thanks for the feedback.

is it possible to run a single sizing in background, i.e. in a separate window? HyperSizer is not usable during the "Analyze/Size"-Process started from the project window, and this sometimes takes an hour.
Using HyperFEA, it opens a separate window, but a single sizing is no option there: either sizing/UpdateFEM/sizing or UpdateFEM/sizing (which of course requires a sizing before).
I need the results after the first sizing, for the original FEM.
If not, I suggest to implement this in the next version.

Yes, the TEMP files are associated via folder name. So if you copy the project's TEMP folder onto a new computer (or the same one after it had been removed) with the same project in a database, HyperSizer should make the association and have all of the data needed to visualize results, generate reports, etc.

Hi Stephen,
that explains it
Can you also tell me if this works simply by folder names? Say, I deleted a project to clean up the database, but have a back-up of the results folder. If I just open a new project, import the old FEM, retrieve the back-up project folder (folder and project name match), will HS show all the results in the FEM-Viewer or is the connection to the results folder lost?
For pressure, HyperSizer uses the same sign convention as Nastran. That is, positive pressure acts in the same direction as the element normal vectors.

You are also correct that the stiffeners of a stiffened panel (including orthogrid) are considered to be on the -Z side of the surface. So to apply the pressure you desire (deflection inward), your pressure should act against the normal vectors, in the -Z direction.
When applying a pressure load on the surface of the panel, what is correct convention for pressure application? I want pressure applied on outer flat surface of ortho grid panel, so that deflection of panel is toward inward side where stiffening ortho grid web is assumed to be located. Looking at images in free body tab, positive pressure is in +Z direction, but is the ortho grid in the -Z side of plate?

Hi Jan,

Sizing results are actually stored outside of the HyperSizer database due to their size. They are stored in your project working folder (default: C:\HyperSizer Data\Projects\Temp).

When you copy a project in HyperSizer, it will prompt you to copy results if desired. Doing so actually copies the TEMP folder for that project and renames it with the new project name.
