Modal buckling analysis in GG

Plug Ins Geometry Gym

Hi, I am trying to perform a modal buckling analysis using Oasys GSA. The goal is to have the complete analysis inside the GUI of Rhino GH, but for the official plugin it is not possible to perform a modal buckling analysis without accessing GSA’s GUI (only Static, p-delta and footfall are possible).
Therefore, I have installed GeometryGym, as it is possible to do this with GG. However, I noticed that the input for the modal buckling solver was a combination case. As I experienced with the official plugin, it is not possible anymore to insert a combination case as an input case; the component gives an error.
Now, using GeometryGym, when I try to run the ggGSASolver in GH, I get no result for the critical buckling factor when using a combination case as input. If I try a static solver and insert a load case, I have no issues in retrieving the strains and displacements. When I try to insert a load case or multiple load cases into the Result Case input of the buckling analysis, I get an error:

  1. Invalid cast: StrLoadCase » LoadCaseCombo

I have followed the example file for obtaining the buckling factor from GG’s info page. Is there something I have missed in building my model? Does anyone know how you could still let the solver work?

We enable some of this advanced functionality “just in time” or on demand as best we can.
If you update the plugin and refer to the attached, does it achieve what you need?
