fedoo.weakform.Inertia

class Inertia(density, name='', space=None)

Weak formulation related to the inertia effect into dynamical simulation.

Used by second-order integrators attached to linear or nonlinear problems.

Parameters:

• density (scalar or arrays of gauss point values.) – Material density. For 1D meshes, this is physically a linear density (mass per unit of length) and for 2D meshes an area density (mass per unit of surface).

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

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