Is Large Deformation Analysis the reality?

Hi guys,

I was wondering if the component 'Large Deformation Analysis' can really simulate the real world physics. Cause the formation is tremendeously determined by the 2 input params: Incremental, MaxDisp, which i do not understand how it works in real world. is it the reality force like gravity, dead load that cause deformation instead of these two params?

Thanks

Lei

Hi Lei,

the 'LargeDeformation'-component of Karamba 1.2.1 is meant as a form-finding tool. It applies a given, user defined load in a number of steps and updates the geometry after each load increment. The number of increments can be defined via the input-plug 'Inc'. The more increments one applies the more accurate the solution will be. Since the procedure is purely incremental, the result will slightly drift off the correct solution. However the displacements will be reasonably exact (see the example 'Examples\TestExamples\Large_Deformation_Analysis\LargeDeformation_Catenary.gh' in the installation directory of Karamba).
When a value is supplied to the input-plug 'MaxDisp' the loads will be scaled such that the maximum displacement of the structure corresponds to that value.

Best,

Clemens
