Stiffness, Mass, and Damping Matrices

Hi,
I want to perform a Frequency Response Analysis for my 2D Warren truss. Is it possible to obtain the stiffness, mass, and damping matrices directly from the Karamba model in the new version of Karamba3D (v3)?

If not, is there an alternative way to calculate these matrices using Karamba?

Thank you for your time and assistance.

Hi,
it is possible to get the stiffness matrix (see SystemStiffnessMatrixRetrieval_scripted.gh in the installed examples under “Scripts”) and the lumped masses (see LumpedMass.gh in the same folder).
The damping matrix can not be retrieved, however it is normally constructed from the stiffness and the mass matrices.

Found it! I really appreciate your answer.
May I ask an additional question? Are feb.Deform and feb.MatSymCSR also accessible in Python 3?

yes, they should.
