3.1.11: Point-Mass

Karamba3D is capable of calculating the natural vibration modes and frequencies of structures (see section 3.5.7). For results to match reality the inertia properties of a structure need to be modelled correctly. Masses of elements (e.g. beams, trusses, shells) are automatically taken care of. All other items need to be included via point-masses.

Be aware of the fact that masses defined with the “Point-Mass”-component do not have a weight but inertia only! However they add to the mass of a model as output at the "Assemble"-component.
