walberla::geometry::initializer::BoundaryFromDomainBorder< BoundaryHandling_T > Class Template Reference

Detailed Description

template<typename BoundaryHandling_T>
class walberla::geometry::initializer::BoundaryFromDomainBorder< BoundaryHandling_T >

Sets a boundary condition at a certain border of the domain (borders are specified by directions).

Configuration file syntax: 

   <initializerID>
   {
       direction    W;         // can be W,E,S,N,T,B  and all
       walldistance 0;         // optional (default to 0),
                               // 0 means the first interior layer is set, -1 means ghost layer
                               // 1 first inner slice ...

      ghostLayersToInitialize  // how many ghost layers are initialized in the direction normal to the border
                               // Example: when initializing northern boundary, the parameter controls how far
                               // the slice goes into the W,E,T,B directions, i.e. how many ghost layers are
                               // initialized in these directions
                               // If this parameter is greater than the existing number of ghost layers,
                               // no error is reported, but all ghostlayers are initialized.
                               // Do not mix up this parameter with the parameter "walldistance" which
                               // specifies the distance of the slice to the (in this example) northern boundary.

       <FlagUID>               {  <boundaryConfiguration>   }
   }

The order of these blocks in the configuration file is important, when regions overlap. later config blocks overwrite the previous ones.

Constructor & Destructor Documentation

◆ BoundaryFromDomainBorder()

template<typename Handling >
walberla::geometry::initializer::BoundaryFromDomainBorder< Handling >::BoundaryFromDomainBorder ( StructuredBlockStorage & blocks,
BlockDataID handlerBlockDataID,
CellInterval globalDomain = CellInterval() )

Constructor for BoundaryFromDomainBorder.

Parameters
blocksthe structured block storage
handlerBlockDataIDthe id of the BoundaryHandler, which type is the template parameter Handling
globalDomainThis parameter can be used if the simulation domain should be smaller than the number of total cells the StructuredBlockStorage has. Instead of using blockStorage.getDomainCellBB() here a custom cell interval can be given. If the empty CellInterval is given (default), the complete domain is used.
