amici.ode_export.Event
- class amici.ode_export.Event(identifier, name, value, state_update, event_observable)[source]
An Event defines either a SBML event or a root of the argument of a Heaviside function. The Heaviside functions will be tracked via the vector h during simulation and are needed to inform the ODE solver about a discontinuity in either the right hand side or the states themselves, causing a reinitialization of the solver.
- __init__(identifier, name, value, state_update, event_observable)[source]
Create a new Event instance.
- Parameters
identifier (
sympy.core.symbol.Symbol
) – unique identifier of the Eventname (
str
) – individual name of the Event (does not need to be unique)value (
sympy.core.expr.Expr
) – formula for the root / trigger functionstate_update (
typing.Optional
[sympy.core.expr.Expr
]) – formula for the bolus function (None for Heaviside functions, zero vector for events without bolus)event_observable (
typing.Optional
[sympy.core.expr.Expr
]) – formula a potential observable linked to the event (None for Heaviside functions, empty events without observable)
