Member Function Documentation

create()

void NavierStokesForce::create ( Storage &  storage, IMaterial &  material  ) const

overridevirtual

Creates all quantities needed by the term using given material.

Called once for every body in the simulation.

Implements IEquationTerm.

Definition at line 254 of file EquationTerm.cpp.

finalize()

void NavierStokesForce::finalize ( IScheduler &  scheduler, Storage &  storage, const Float  t  )

overridevirtual

Computes all the derivatives and/or quantity values based on accumulated derivatives.

Called every time step after derivatives are evaluated and saved to storage.

Todo:

rotation rate tensor?

Implements IEquationTerm.

Definition at line 233 of file EquationTerm.cpp.

initialize()

void NavierStokesForce::initialize ( IScheduler &  scheduler, Storage &  storage, const Float  t  )

overridevirtual

Initialize all the derivatives and/or quantity values before derivatives are computed.

Called at the beginning of every time step. Note that derivatives need not be zeroed out manually, this is already done by timestepping (for derivatives of quantities) and solver (for accumulated values).

Implements IEquationTerm.

Definition at line 227 of file EquationTerm.cpp.

setDerivatives()

void NavierStokesForce::setDerivatives ( DerivativeHolder &  derivatives, const RunSettings &  settings  )

overridevirtual

Sets derivatives required by this term.

The derivatives are then automatically evaluated by the solver, the equation term can access the result in finalize function. This function is called once for each thread at the beginning of the run.

derivatives.require<StressDivergence>(derivatives, settings);

Implements IEquationTerm.
