algorithmic modeling for Rhino
I am trying to calculate a double layer grid shell in Karamba and I don’t know how to model compatibles nodes between bars.
What I mean with compatibles nodes is that i am searching to have the bars H and V continuous but the joint between them to be defined in such a way that node displacements are identical, while rotation in nodes can differ (an articulation).
In the link below you can find an example of how it use in Robot Autodesk:
So my question is how can I implement in Karamba 'compatibles nodes' such as Robot Autodesk does or similar.
In Karamba 1.2.2. joints can be defined in three ways:
For details please see the manual.
Thank you for your answer but my question wasn’t really about joints but about a specific joint that I don’t know how to simulate in Karamba.
Maybe because of my bad English the question was not very clear. Attached you can find some schemas that I hope it will be more clarifying.
PIC1: The bars H and V of the grid shell are continuous but at their intersection are articulated one relative to the other.
In the Det A is presented this type of joint that I am searching to simulate in Karamba. The only idea that I have for the moment ( but is not proper and quite difficult to integrate) is to introduce a fictional bar be-articulated between bars H and V.
So is it there another solution for my problem (despite that presented in the DET A) ?
you could model the connections using a springs. A spring can be oriented like a beam element and allows to freely chose its stiffness properties.
The 'ElementFelting'-component should be useful for automatically generating the connections (see manual and examples).
