Detailed Description

template<class GB, class = std::void_t<>>
class AMDiS::GlobalBasisIdSet< GB, class >

Provide global ids for all DOFs in a global basis.

A GlobalBasisIdSet provides and interface to retrieve unique IDs (over all partitions) for all DOFs in the basis. It is implemented in terms of the NodeIdSet for each basis node that locally on each element calculates a global unique id.

Examples:

GlobalBasisIdSet<Basis> idSet(basis);
for (const auto& e : elements(basis.gridView())) {
idSet.bind(e);
for (std::size_t i = 0; i < idSet.size(); ++i) {
auto id = idSet.id(i); // global unique ID of i'th local DOF
auto pt = idSet.partitionType(i); // partition type of i'th local DOF
}
idSet.unbind();
}
AMDiS::GlobalBasisIdSet
Provide global ids for all DOFs in a global basis.

◆ bind()

void bind ( Element const &  element)
inline

Bind the IdSet to a grid element.

Binding the IdSet to an element collects the ids from all DOFs on that element and stores it in a local vector. Thus, the global DOF ids can be extracted using id() afterwards cheaply.
