Get Results From Different Subcases
Hey!
I am trying to perform a Linear Buckling analysis following a step-by-step video that was posted in Altair How-To youtube channel (EP20: Linear Buckling Analysis). I did everything that was in the video. When I open Hyperview to get the results, there are only the results from the linear static analysis, even though I created two subcases. A friend of mine tried to perform a buckling analysis following the same video and he was able to find the two subcases in Hyperview. I opened the .hw file that he created and I finally was able to get the same results as him. This led me to think that it possibly is something related to some default setting from installation. Thank you for your attention.
A little note: at the moment I am writing this message, the program has been installed on my computer for about an hour. I haven't changed no settings.

Hello, Henry.
Check if both subcases are set to export in the Entity State Browser:
When exporting, if you have unchecked entities and select Custom, they won't be exported to you solver deck
For the model you reported having only one subcase in the results file, you can check if both subcases were exported to the .fem file, by opening it with a text editor
Let me know if this is your case. But if they're both exported and you only have result for one subcase, it's probably a solver run issue.

I've done everything you've mentioned, the two subcases are exported to the .fem file and still only one of them shows up in Hyperview

Henry,
Please check the .out file in the run folder. See if there are errors.
If you wish, share the .fem and .out files so I can also investigate it.

Hey Paulo,
Here are the .fem and .out files. I've taken a look at the .out file and I wasn't able to find anything.

Hello, Henry.
In the .out file, there's the following warning:
Reviewing your model, I noticed that the FORCE loads are applied as tension instead of compression. This condition wouldn't induce buckling behavior:
If you change direction to -X, it should be able to run:

Paulo Libório.Oh wow... I thought that doing that the program would yield negative eigenvalues. I didn't even think it would be that because some other software actually allow you to that. Thank you!

I am having the same issue with the 2022.3 version, the same .hm file generates the .fem file with the subcase in hypermesh but not in hyperworks. Both the subcases are set to active and export. Even cross checked it in the export window.
