PointIntegralSolver¶

class dolfin.cpp.fem.PointIntegralSolver¶

Bases: dolfin.cpp.common.Variable

This class is a time integrator for general Runge Kutta forms. It only includes Point integrals with piecewise linear test functions. Such problems are disconnected at the vertices and can therefore be solved locally.

Constructor FIXME: Include version where one can pass a Solver and/or Parameters

Parameters:	MultiStageScheme > scheme (std::shared_ptr<) –

static default_parameters()¶

num_jacobian_computations()¶

Return number of computations of jacobian.

Return type:	std::size_t

reset_newton_solver()¶

Reset newton solver.

Return type:	void

reset_stage_solutions()¶

Reset stage solutions.

Return type:	void

step()¶

Step solver with time step dt.

Parameters:	dt (double) –
Return type:	void

step_interval()¶

Step solver an interval using dt as time step.

Parameters:	t0 (double) – t1 (double) – dt (double) –
Return type:	void
