Detailed Description

Activation function classes for cardiac chamber models.

Enumeration Type Documentation

strong

Type of signal an ActivationFunction produces.

Used to catch mismatched activation_function/active_stress pairings: an ActiveStress model declares the signal type it needs via ActiveStress::required_signal_type, and ChamberSphere::setup_dofs checks it against the chamber's ActivationFunction::signal_type.

Enumerator
normalized	f(t) in [0, 1], used by most activation functions
rate	Signed reaction-rate signal u(t), used by PiecewiseRateActivation
