Module Contents¶
- class pyHarm.Elements.ABCElement.ABCElement(nh: int | list[int], nti: int, name: str, data: dict, CS: pyHarm.CoordinateSystem.CoordinateSystem, dynop: dict[str, numpy.ndarray] | None = None)¶
Bases:
abc.ABCThis 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.

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.
