Parametric frame in karamba does not deflect properly

I made a frame that is loaded horizontally. But two thing are going wrong.

First the points of supports and the points where the horizontal load are applied are only visible at a certain combination of parameters.

For all other combinations, only one row is supported and only one column has horizontal loads.

The second problem is that the deflection of beams is not consistent. It seems that only the outer beams are being deflected and the inner beams remain straight.

I think the problem lies in the way that I constructed my geometry. Instead of filtering out the points that I needed of the made geometry, I made extra arrays of points to define the points of support and the points of wind loading. These points have the exact coordinates, but apparently karamba does not link these two but sees them as separate.

What modifications should I make to get this frame working?

Hi Rayaan,

Here are some points:

1. you currently have multiple models - flatten your input supports and loads to eliminate this issue

2. some of the load points are not actually points on the curve geometry in the model - they might lie somewhere in the middle of one curve, but you would then need to split these curves at that point should you wish to use this for the position for your loads.

best,

Matthew
