Member Enumeration Documentation

inactivTypes

enum concepts::CellCondition::inactivTypes

Different types to handle inactive cells

ACTIVE is the default type.

INACTIVE means, that these cells are in no support of any basis function. Basis functions are cut on boundary of these cells. are no degrees of freedom inside the cell.

INACTIVEPLUS means, that additionally the degrees of freedom on the boundary of the cell are set to passive.

SWITCH_ON builds only the degrees of freedom specified in the set of attributes. Inner degrees of freedom are not built.

SWITCH_OFF builds every degree of freedom except for the ones specified in the attributes set.

DIVIDE takes the degrees of freedom on a facette (edge or face) in the interior such that the degrees of freedom are doubled.

SWITCH_ON and SWITCH_OFF only work for degrees of freedom on the boundary of the cell. For inner degrees of freedom consider the class BuildH1InnerTColumnsLinTrunk in /hp2D/buildH1TColumns.hh. Consider that one cell cannot have two different CellCondition objects. The last inserted one will be the one CellConditions.add(...) is keeping.

REMARK: Be carefull with edge and vertex attributes. If an edge with attribute "a" has a vertex with no attribute, than the vertex degree of freedom will be treated the same way as the edge (SWITCH_ON or SWITCH_OFF). However, this does not apply for adjacent cells with the same vertex. If the vertex in the adjacent cell is to be treated in the same then the vertex itself needs to have the attribute "a". On the other hand, if the vertex has its own attribute, then it is independent of the edge. This method implies that you must respect a further consistency condition within each cell with cellCondition: If ever two adjacent edges have different non zero attributes, the vertex in between them needs its own attribute. By violating this condition you will produce an assertion error. If one of the edge attributes is zero (i.e. the edge has no attribute) the vertex will get the attribute of the other edge or else will also have no attribute if the two edges do not have attributes. Note that this is done in each cell separately, thus there are only two edges a vertex.

Examples for the usage of CellCondition can be found in /geometry/testsuite/testCC.cc or in /hp2D/testsuite/cellconditionsTest.cc.
