Detailed Description

template<int D>
class ThunderEgg::VarPoisson::StarPatchOperator< D >

Implements a variable coefficient Laplacian f=Div[h*Grad[u]].

h is a cell-centered coefficient

Template Parameters

D	the number of Cartesian dimensions

Constructor & Destructor Documentation

StarPatchOperator()

template<int D>

ThunderEgg::VarPoisson::StarPatchOperator< D >::StarPatchOperator ( const Vector< D > &  coeffs, const Domain< D > &  domain, const GhostFiller< D > &  ghost_filler  )

inline

Construct a new StarPatchOperator object.

Parameters

coeffs	the cell centered coefficients
domain	the Domain associated with the operator
ghost_filler	the GhostFiller to use before calling applySinglePatch

Member Function Documentation

addDrichletBCToRHS()

template<int D>

void ThunderEgg::VarPoisson::StarPatchOperator< D >::addDrichletBCToRHS ( Vector< D > &  f, std::function< double(const std::array< double, D > &)>  gfunc, std::function< double(const std::array< double, D > &)>  hfunc  )

inline

Helper function for adding Dirichlet boundary conditions to right hand side.

Parameters

f	the right hand side vector
gfunc	the exact solution
hfunc	the coefficients

applySinglePatch()

template<int D>

void ThunderEgg::VarPoisson::StarPatchOperator< D >::applySinglePatch ( const PatchInfo< D > &  pinfo, const PatchView< const double, D > &  u_view, const PatchView< double, D > &  f_view  ) const

inlineoverridevirtual

Apply the operator to a single patch.

The ghost values in u will be updated to the latest values, and should not need to be modified

Parameters

pinfo	the patch
u_view	the solution
f_view	the left hand side

Implements ThunderEgg::PatchOperator< D >.

applySinglePatchWithInternalBoundaryConditions()

template<int D>

void ThunderEgg::VarPoisson::StarPatchOperator< D >::applySinglePatchWithInternalBoundaryConditions ( const PatchInfo< D > &  pinfo, const PatchView< const double, D > &  u_view, const PatchView< double, D > &  f_view  ) const

inlineoverridevirtual

Apply the operator to a single patch.

The ghost values in u will be updated to the latest values, and should not need to be modified

Parameters

pinfo	the patch
u_view	the solution
f_view	the left hand side

Implements ThunderEgg::PatchOperator< D >.

clone()

template<int D>

StarPatchOperator<D>* ThunderEgg::VarPoisson::StarPatchOperator< D >::clone ( ) const

inlineoverridevirtual

Get a clone of this operator.

Returns

StarPatchOperator<D>* a newly allocated copy of this operator

Implements ThunderEgg::PatchOperator< D >.

modifyRHSForInternalBoundaryConditions()

template<int D>

void ThunderEgg::VarPoisson::StarPatchOperator< D >::modifyRHSForInternalBoundaryConditions ( const PatchInfo< D > &  pinfo, const PatchView< const double, D > &  u_view, const PatchView< double, D > &  f_view  ) const

inlineoverridevirtual

Treat the internal patch boundaries as domain boundaires and modify RHS accordingly.

This will be u_viewed in patch solvers to formulate a RHS for the individual patch to solve for.

Parameters

pinfo	the patch
u_view	the left hand side
f_view	the right hand side

Implements ThunderEgg::PatchOperator< D >.
