Detailed Description

Calculates GeomShapes using barycenters.

This class allows updating the coordinates of the nodes of a GeomShape and calculating its center and the center of its faces using the barycenter formula. These coordinates must be updated as soon as one of the mesh nodes moves.

All methods of this class are static and it is therefore not useful to create instances.

There are several ways to update:

• via computeAll(GeomShapeMng& shape_mng,VariableNodeReal3& coords,const CellGroup& cells), in which case all GeomShapes of the cells in cells are updated. This is the most performant method if a large number of cells must be updated.
• via computeAll(GeomShapeMutableView elem,const VariableNodeReal3& coords,Cell cell) if you wish to update cell by cell.

compute()

template<GeomType ItemType>

void Arcane::geometric::BarycentricGeomShapeComputer::compute ( GeomShapeMutableView elem )

static

Template method.

The template parameter ItemType must correspond to one of the following types: GeomType::Triangle3, GeomType::Quad4, GeomType::Tetraedron4, GeomType::Pyramid5, GeomType::Pentaedron6, GeomType::Hexaedron8, GeomType::Heptaedron10, GeomType::Octaedron12.

The coordinates of the nodes of elem must already have been positioned, for example via the call to setNodes().

The call is made by specifying the cell type as defined in ArcaneTypes.h. For example, for a Quad4:

Cell cell = ...;
GeomShapeMng shape_mng = ...;
GeomShapeMutableView shape_view(shape_mng.mutableShapeView(cell));
BarycentricGeomShapeComputer::compute<GeomType::Quad4>(shape_view);
