Use the boolean toogle to pass from the basic pattern analysis to the optimize one. This video looks at using the Grasshopper plug in Karamba 3D to analyze two different load cases. I could only wonder if there is a problem with my script or if there is a bug somewhere in Karamba programming. Karamba 3D is a finite element analysis tool used to analyz. I'm really can't explain this difference, and it's was certainly not the kind of result that I want to show. This one showing greater deformation than the original basic pattern.

Unfortunatly, after doing a cycle of optimization, the new dome show, in RFEM, great amelioration, but I obtain the exact opposite result in Karamba. As conclude, I still can use the ratio of the values to optimize my dome panel pattern. Even if annoying it was not discarting the benefit of Karamba since the deformation and force distribution were similar to the RFEM model. I first encounter very different values between the Karamba and RFEM models (at this point, I suspect the material proprieties - isotropic and calculation method to explain the difference). My ultimate purpose is to demonstrate the advantage of working with Karamba in a iterative design process for non-standard wood construction in CLT by using structural analysis as input to optimize the form.

I'm doing a structural analysis comparaison for a wood panels dome between Karamba and RFEM.
