setup_container()

void amr_wind::actuator::Actuator::setup_container ( )

private

Set up the container for sampling velocities

Allocates memory and initializes the particles corresponding to actuator nodes for all turbines that influence the current MPI rank. This method is invoked once during initialization and during regrid step.

update_positions()

void amr_wind::actuator::Actuator::update_positions ( )

private

Update actuator positions and sample velocities at new locations.

This method loops over all the turbines local to this MPI rank and updates the position vectors. These new locations are provided to the sampling container that samples velocities at these new locations.

update_velocities()

void amr_wind::actuator::Actuator::update_velocities ( )

private

Provide updated velocities from container to actuator instances
