Hi Manjit Patil,

it means that your system is kinematic: It can move without deforming. This can happen in case of an insufficient number of supports or when a system is not properly connected. Use the 'Connected Parts'-component of Karamba to check whether your model consists of one piece. In a second step feed you model into the 'Eigen Modes' component. The first eigen-mode should show the rigid body mode in question. Activate the display of local axes in the 'Model View'-component to see also the possible axial rotation of beams.

Clemens

Hello Clemens,

Thanks for the reply.To make my model work with karamba, I am analyzing part of my full model. Karamba undergoes analysis but the results of the beam view are not displayed in the rhino view. Will you please invest some time and go through my script.

Thanking you.

Regards,

Manjit Patil

Hello Manjit,

the definition contained two problems:

• The input to the Assemble-component needs to be flattened in your case. Otherwise multiple, incomplete models result. Enable 'Draw Fancy Wires' in the GH 'Display'-menu: this gives you a hint whether single objects, lists or data trees are passed around in the connections.
• Karamba assumes the input geometry to be given in meters (or feet in case of using Imperial units). The model has a size of 11000m.

Best,

Clemens

Hell Clemens,

Is their any way to apply UDL(UniformDistributed Load) to beam AA, BB, CC and DD. But the load on AA will be more than that of BB. The load on BB will be more than that of CC and henceforth. I tried this using Line load component but it didn't work.

Thank you.

Regards,

Manjit Patil

Hello Manjit,

it can be done - however this is more a Grasshopper issue. A Karamba solution would be to superimpose multiple mesh-loads.

Hi,

I am getting the same error message as Manjit but can't figure out why.

Could anyone possibly help me out?

Thanks,

Annabel

Hi,

I think I've sorted it now.

However, I am looking for a result more like the attached image.  Any ideas?

Thanks,

Annabel
