Detailed Description

Rescales the thermodynamic pressure gradient scaling the acoustic propagation speeds to allow for a larger time step. See: DesJardin, Paul E., Timothy J. O’Hern, and Sheldon R. Tieszen. "Large eddy simulation and experimental measurements of the near-field of a large turbulent helium plume." Physics of fluids 16.6 (2004): 1866-1883.

Member Function Documentation

GetId()

const std::string& ablate::finiteVolume::processes::PressureGradientScaling::GetId ( ) const

inlineoverridevirtual

only required function, returns the id of the object. Should be unique for the simulation

Returns

Implements ablate::io::Serializable.

Restore()

PetscErrorCode ablate::finiteVolume::processes::PressureGradientScaling::Restore ( PetscViewer  viewer, PetscInt  sequenceNumber, PetscReal  time  )

overridevirtual

Restore the state from the PetscViewer

Parameters

viewer
sequenceNumber
time

Implements ablate::io::Serializable.

Save()

PetscErrorCode ablate::finiteVolume::processes::PressureGradientScaling::Save ( PetscViewer  viewer, PetscInt  sequenceNumber, PetscReal  time  )

overridevirtual

Save the state to the PetscViewer

Parameters

viewer
sequenceNumber
time

Implements ablate::io::Serializable.

Setup()

void ablate::finiteVolume::processes::PressureGradientScaling::Setup ( ablate::finiteVolume::FiniteVolumeSolver &  fv )

overridevirtual

Function to setup timestepping with the PressureGradientScaling. This can be called multiple times and will only be registered once

Returns

Implements ablate::finiteVolume::processes::Process.

UpdatePreconditioner()

PetscErrorCode ablate::finiteVolume::processes::PressureGradientScaling::UpdatePreconditioner	(	TS	flowTs,
		ablate::solver::Solver &	flow
	)

function to compute the average density in the domain

Parameters

flowTs
flow

Returns
