Functions

`do`(Sol, flux, lmbda, ud, th, elem, ...)	Reconstruct the limited slopes at the cell interfaces.
`get_conservatives`(U, ud, th)	Get advected (conservative) quantities at the left and right of the cell interfaces.
`limiters`(limiter_type, al, ar)	Applies the limiter type specified in the initial conditions to recovery the slope.
`slopes`(Sol, Diffs, ud, elem)	Reconstruct the piecewise linear slopes in the cells from the piecewise constants in the cell and its neighbours.

src.dycore.physics.gas_dynamics.recovery.do(Sol, flux, lmbda, ud, th, elem, split_step, tag)#

Reconstruct the limited slopes at the cell interfaces.

Parameters#

Solmanagement.variable.Vars: Solution data container on cell centers.
fluxmanagement.variable.States: Flux data container on cell interfaces.
lmbdafloat: \(\frac{dt}{dx}\), where \(dx\) is the grid-size in the direction of the substep.
udinputs.user_data.UserDataInit: Class container for the initial condition.
thphysics.gas_dynamics.thermodynamic.init: Class container for the thermodynamical constants.
elemdiscretization.kgrid.ElemSpaceDiscr: Class container for the cell-grid.
split_stepint: Tracks the substep in the Strang-splitting.
tagNone or rk: Default is None which uses a second-order Strang-splitting. rk toggles a first-order Runge-Kutta update for the advection scheme.

management.variable.States, management.variable.States: Lefts, Rights are containers for the advected quantities at to the left and the right of the cell interfaces.

src.dycore.physics.gas_dynamics.recovery.slopes(Sol, Diffs, ud, elem)#

Reconstruct the piecewise linear slopes in the cells from the piecewise constants in the cell and its neighbours.

Solmanagement.variable.Vars: Solution data container
Diffsmanagement.variable.States: Data container for the difference in the quantities between adjacent cells, (right - left).
udinputs.user_data.UserDataInit: Data container for the initial conditions
elemdiscretization.kgrid.ElemSpaceDiscr: Data container for the cell grid.

management.variable.Characters: Reconstructed piecewise linear slopes in the cell.

src.dycore.physics.gas_dynamics.recovery.limiters(limiter_type, al, ar)#

Applies the limiter type specified in the initial conditions to recovery the slope.

limiter_typemanagement.enumerator.LimiterType: LimiterType list
almanagement.variable.States: Left indices of the Diffs array for the respective quantities.
armanagement.variable.States: Right indices of the Diffs array for the respective quantities.

For now, only the limiter type NONE is supported. This takes \(\frac{(al + ar)}{2}\).

src.dycore.physics.gas_dynamics.recovery.get_conservatives(U, ud, th)#

Get advected (conservative) quantities at the left and right of the cell interfaces.

Umanagement.variable.States: Lefts and Rights corresponding to the values at the cell interfaces.
udinputs.user_data.UserDataInit: Data container for the initial conditions
thphysics.gas_dynamics.thermodynamic.init: Class container for the thermodynamical constants.
