Karamba3D is an interactive, parametric finite element program. It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads.

Karamba3D is being developed by Clemens Preisinger in cooperation with Bollinger und Grohmann ZTGmbH in Vienna.

Dear RubberDuck,

Christoph will make a separate assembly of the custome components and publish it on Food4Rhino. But this may take some time.

Effectively thats right. If you have two pins in the same support plane then the second pin will restrict the model from utilising the rollers.

 

Restraint conditions are, in my opinion, one of the trickiest things to understand when you start modelling.

Thank you for the tip Joshua.

So If I want to lean my space truss on:

2 supports, I need:

1 pinned and 1 roller support?

 

3 supports, I need:

1 pinned, and 2 roller supports

 

4 supports, I need:

1 pinned, and 3 rollers supports

 

5 supports, I need:

1 pinned, and 4 roller supports

 

...

 

?

Might be valuable to those playing with this. If you don't understand how these affect your model you might want to do some research on statics and have a read of this little pdf here.

Thanks, That was dumb of me. Model Working.
Comment by Karamba3D on September 27, 2011 at 1:44pm
Joshua, fix the beams rotation about its longitudinal axis (Rx) at one support then your example works. Otherwise the example is kinematic.
Comment by Karamba3D on September 27, 2011 at 1:39pm
we have examples and will upload them on the karamba website as soon as possible.

Do you have functioning models we can use to learn with? I looked on the website but I couldn't find any. It would be a very useful learning tool especially for a simple problem like a beam so we can start calibrating our results against other software i.e. space gass.

Simple%20Beam%20Karamba.gh

 

Building a basic model to calibrate for a paper I am working on. I noticed that the length can cause issues with the model results. When it is set to 40m on the first slider, it doesnt work. Then set it to 39.75m and it works. This happens across the whole slider range at random points.

 

Have I missed something?

I see now. I have a "null" member. It has no force in it.

Sorry for disturbance.
