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.

Member Function Documentation

§ initialize()

template<int dim>
virtual 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_particleAn iterator to the first particle to be moved.
[in]end_particleAn iterator to the last particle to be moved.
[in]old_velocitiesThe velocities at t_n, i.e. before the particle movement, for all particles between begin_particle and end_particle at their current position.
[in]velocitiesThe 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]dtThe 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 >.

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 101 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 108 of file rk_4.h.

§ property_index_k

template<int dim>
std::array<unsigned int,4> aspect::Particle::Integrator::RK4< dim >::property_index_k
private

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