| virtual EntityShape * | getEntityShape (int type)=0 |
| Get the sub-descriptor for this entity type. | |
| virtual bool | hasNodesIn (int dimension)=0 |
| Return true iff there are nodes on entities of this dimension. | |
| virtual int | countNodesOn (int type)=0 |
| Return the number of nodes associated with an entity of this type. | |
| virtual int | getOrder ()=0 |
| Return the polynomial order of the shape functions. | |
| virtual void | getNodeXi (int type, int node, Vector3 &xi) |
| Get the parent element coordinates of an element node. | |
| virtual const char * | getName () const =0 |
| Get a unique string for this shape function scheme. | |
Describes field distribution and shape functions.
these classes are typically singletons, one for each shape function scheme
| virtual int apf::FieldShape::countNodesOn | ( | int | type | ) | [pure virtual] |
Return the number of nodes associated with an entity of this type.
in a linear mesh, nodes are associated with vertices but there are no nodes associated with other entities.
| type | select from apf::Mesh::Type |
| virtual EntityShape* apf::FieldShape::getEntityShape | ( | int | type | ) | [pure virtual] |
Get the sub-descriptor for this entity type.
| type | select from apf::Mesh::Type |
| virtual void apf::FieldShape::getNodeXi | ( | int | type, | |
| int | node, | |||
| Vector3 & | xi | |||
| ) | [virtual] |
Get the parent element coordinates of an element node.
| type | element type, select from apf::Mesh::Type | |
| node | index from element node ordering | |
| xi | parent element coordinates |
| virtual int apf::FieldShape::getOrder | ( | ) | [pure virtual] |
Return the polynomial order of the shape functions.
this is not always applicable
| virtual bool apf::FieldShape::hasNodesIn | ( | int | dimension | ) | [pure virtual] |
Return true iff there are nodes on entities of this dimension.
this is used to skip dimensions in loops
