fedoo.weakform.RotaryInertia

class RotaryInertia(rotary_inertia, name='', space=None)

Rotary inertia effect into dynamical simulation.

Used for fedoo.problem.Newmark, fedoo.problem.NonLinearNewmark

Parameters:

• rotary_inertia (list or scalar or arrays of gauss point values.) – mass moment of inertia. For 1D meshes, the rotary inertia is understood per unit of length and for 2D meshes per unit of surface. If list, defines the inertia along each axis (generally using local coordinate system), e.g in 3D: [x_rot_inertia, y_rot_inertia, z_rot_inertia]

• name (str, optional) – name of the WeakForm

• space (ModelingSpace, optional) – Modeling space used to build the weak form. Default to active one.
