Hi Karamba forums, I am trying to verify my Karamba results with an additional FEM software but the masses of my model and the exported model to FEM-design vary slight, and I believe that this is due to the inner radius of the SHS cross section differing. In FEM-design and according to Eurocode the inner radius for hot rolled SHS profiles are 1*t, but from this previous thread (How to get Internal Fillet Radius from a Cross Section?) I get that the inner radius is calculated as fillet_r1_ = fillet_r - w_thick for when fillet_r1 is > 0, and where fillet_r1 is the inner radius. This differs from the radius I need to confirm my results, is there any way to change the inner radius? I am using the cross section component. Thanks!
Hi @Rick8, here is a definition which shows how to define the inner and outer fillet radius of box cross sections in Karamba3D:
RHSCrossSectionDefinition.gh (3.9 KB).

Edit: I think its working, but is there any way to not have to adress the assemblies everytime?
@Rick8: At the moment there is no way around addressing the assemblies when using a GH script component.
Alternatively you could compile a component using VSCode. Then it needs to be named in such a way that it comes alphanumerically after “Karamba” and thus gets loaded by GH after Karamba3D.
