algorithmic modeling for Rhino
I have problems getting the analysis from GSA for the GH defintion made with the help of Geometry Gym plugin. My model is analysed without any errors in GH and displays the results for Axial force, shear force, and bending moment on Rhino.
However, it fails to be analysed on GSA itself. On GSA it shows the geometry and loading (point loads are 6kN, but it shows as 5000 N/pic.cm), but it shows zero reaction forces and zero internal forces.
I tried it both on my laptop and PC. The versions on my laptop are the latest for all Rhino, Grasshopper, Geometry Gym, and GSA.
The GH definition is attached below.
Hi, Why you do not use Millipede to do analysis in GH. This simplify everything.
Thanks for posting. Can you provide some further information? What does GSA report as it solves. Below is what I see for the attached resulting model.
It sounds odd, if the results are returned to GSA, it is solving. You might have to reset result scales using the GSA button.
