Detailed Description

template<int dim>
class aspect::Particle::Integrator::RK4< dim >

Runge Kutta fourth order integrator. This scheme requires storing the original location and intermediate k1, k2, k3 values in the particle properties.

Definition at line 40 of file rk_4.h.

Constructor & Destructor Documentation

§ RK4()

template<int dim>

aspect::Particle::Integrator::RK4< dim >::RK4 ( )

Member Function Documentation

§ initialize()

template<int dim>

void aspect::Particle::Integrator::RK4< dim >::initialize ( )

overridevirtual

Look up where the RK4 data is stored. Done once and cached to avoid repeated lookups.

Reimplemented from aspect::Particle::Integrator::Interface< dim >.

§ local_integrate_step()

template<int dim>

void aspect::Particle::Integrator::RK4< dim >::local_integrate_step	(	const typename ParticleHandler< dim >::particle_iterator &	begin_particle,
		const typename ParticleHandler< dim >::particle_iterator &	end_particle,
		const std::vector< Tensor< 1, dim >> &	old_velocities,
		const std::vector< Tensor< 1, dim >> &	velocities,
		const double	dt
	)

overridevirtual

Perform an integration step of moving the particles of one cell by the specified timestep dt. This class implements a Runge-Kutta integration scheme that is fourth order accurate in space.

Parameters

[in]	begin_particle	An iterator to the first particle to be moved.
[in]	end_particle	An iterator to the last particle to be moved.
[in]	old_velocities	The velocities at t_n, i.e. before the particle movement, for all particles between `begin_particle` and `end_particle` at their current position.
[in]	velocities	The velocities at the particle positions at t_{n+1}, i.e. after the particle movement. Note that this is the velocity at the old positions, but at the new time. It is the responsibility of this function to compute the new location of the particles.
[in]	dt	The length of the integration timestep.

Implements aspect::Particle::Integrator::Interface< dim >.

§ new_integration_step()

template<int dim>

bool aspect::Particle::Integrator::RK4< dim >::new_integration_step ( )

overridevirtual

This function is called at the end of every integration step. For the current class it will either increment the step variable and return true to request another integration step, or reset the step variable to 0 and return false if we are already in step 4.

Returns: This function returns true if the integrator requires another integration step. The particle integration will continue to start new integration steps until this function returns false.

Reimplemented from aspect::Particle::Integrator::Interface< dim >.

§ required_solution_vectors()

template<int dim>

std::array<bool, 3> aspect::Particle::Integrator::RK4< dim >::required_solution_vectors ( ) const

overridevirtual

Return a list of boolean values indicating which solution vectors are required for the integration. The first entry indicates if the particle integrator requires the solution vector at the old old time (k-1), the second entry indicates if the particle integrator requires the solution vector at the old time (k), and the third entry indicates if the particle integrator requires the solution vector at the new time (k+1).

The RK4 integrator requires the solution vector at the old time (k) for the first integration step, the solution vector at both the old and new time for the second and third integration steps and the solution vector at the new time (k+1) for the fourth integration step.

Implements aspect::Particle::Integrator::Interface< dim >.

Member Data Documentation

§ n_integrator_properties

template<int dim>

const unsigned int aspect::Particle::Integrator::RK4< dim >::n_integrator_properties = 4*dim

static

We need to tell the property manager how many intermediate properties this integrator requires, so that it can allocate sufficient space for each particle. However, the integrator is not created at the time the property manager is set up and we can not reverse the order of creation, because the integrator needs to know where to store its properties, which requires the property manager to be finished setting up properties. Luckily the number of properties is constant, so we can make it a static property of this class. Therefore, the property manager can access this variable even before any object is constructed.

The Runge-Kutta 4 integrator requires 4 tensors with dim components each.

Definition at line 117 of file rk_4.h.

§ integrator_substep

template<int dim>

unsigned int aspect::Particle::Integrator::RK4< dim >::integrator_substep

private

The current integration step, i.e. for RK4 a number between 0 and 3.

Definition at line 124 of file rk_4.h.

§ property_indices

template<int dim>

std::array<unsigned int,4> aspect::Particle::Integrator::RK4< dim >::property_indices

private

The location of the 4 RK4 data fields stored in the particle properties.
