Detailed Description

template<size_t Dim, typename TargetFrame>
class ElementMap< Dim, TargetFrame >

The CoordinateMap for the Element from the Logical frame to the TargetFrame

An ElementMap takes a CoordinateMap for a Block and an ElementId as input, and then "prepends" the correct affine map to the CoordinateMap so that the map corresponds to the coordinate map for the Element rather than the Block. This allows DomainCreators to only specify the maps for the Blocks without worrying about how the domain may be decomposed beyond that.

Constructor & Destructor Documentation

◆ ElementMap()

template<size_t Dim, typename TargetFrame >
ElementMap< Dim, TargetFrame >::ElementMap ( const ElementId< Dim > &  element_id,
const Block< Dim > &  block 
)

Construct from an element_id within the block. The (affine) ElementLogical to BlockLogical map is determined by the element_id. The BlockLogical to TargetFrame map is determined by the block:

  • If the block is time-independent: the block.stationary_map() is used.
  • If the block is time-dependent: The block.moving_mesh_*_map() maps are used. Which maps are used depends on the TargetFrame.
