Class for prolongation of multigrid residual onto a finer grid.
- Note
- This class only does constant prolongation. Using Chombos EBMGInterp with piecewise linear (bi/tri-linear) did not improve multigrid convergence.
◆ EBMGProlong()
| EBMGProlong::EBMGProlong |
( |
const EBLevelGrid & |

noexcept |
Full constructor. Calls the define function.
- Parameters
-
| [in] | a_eblgFine | Fine level that we prolong to. |
| [in] | a_eblgCoar | Coarse level that we prolong from. |
| [in] | a_refRat | Refinement factor between levels. |

Define function.
- Parameters
-
| [in] | a_eblgFine | Fine level that we prolong to. |
| [in] | a_eblgCoar | Coarse level that we prolong from. |
| [in] | a_refRat | Refinement factor between levels. |

Prolong residual onto the coarse grid.
- Parameters
-
| [in,out] | a_fineData | Fine-grid residual. |
| [in] | a_coarData | Coarse-grid residual |
| [in] | a_variables | Variables to prolong. |
◆ m_prolongStencils
| LayoutData<BaseIVFAB<VoFStencil> > EBMGProlong::m_prolongStencils |
|
protected |
Prolongion stencils near the EB.
The stencils are defined on the fine grid but their vofs reach into the coarse grid.
