Initial Value Problem Interface (i_initial_value_problem)

class pypint.problems.i_initial_value_problem.IInitialValueProblem(*args, **kwargs)

Bases: pypint.problems.i_problem.IProblem, pypint.problems.transient_problem_mixin.TransientProblemMixin

Basic interface for initial value problems.

Parameters:initial_value (numpy.ndarray) – Initial value of \(u(t_0,\phi(t_0))\) with \(t_0\) being the time interval start.

initial_value

Accessor for the initial value.

Parameters:

initial_value (numpy.ndarray) – Initial value of the solution.

Returns:

initial_value – Initial value of the solution.

Return type:

numpy.ndarray

Raises:

ValueError –

• if initial_value is not a numpy.ndarray with shape of IProblem.dim
• if initial_value‘s size is not equal the number of spacial IProblem.dim
