This is the abstract class ruling the element class.

An element consists in an elementary contribution to the residual equations.

Parameters:

• nh (int) – number of harmonics.

• nti (int) – number of time steps.

• name (str) – name given to the kinematic condition.

• data (dict) – dictionary containing all the definition information of the kinematic condition.

• CS (CoordinateSystem) – local or global coordinate system the kinematic condition is defined on.

flag_nonlinear

if True, the element is nonlinear.

Type:

bool

flag_AFT

if True, the element requires an alternating frequency/time domain procedure for computing residuals.

Type:

bool

flag_extforcing

if True, the element is an external forcing.

Type:

bool

flag_DLFT

if True, the element uses the dynamic Lagrangian method for computing the residuals.

Type:

bool

flag_adim

if True, the element is adimentioned.

Type:

bool

nh
