Member Function Documentation

void sfem::mesh::DofHandler::reallocateGlobalDofs

(

const mesh::MeshAssembly &

structure

)

reallocates and resets available dof settings determines how many dofs are available and determine which available dof is linked to which node

Parameters:

structure

... is the FE structure to be analyzed

Member Data Documentation

std::vector< std::vector<index_type> > sfem::mesh::DofHandler::global_mechanical_displacements_index_from_node_index [protected]

determines the indices of nodal dofs in the global available_disp vector Usage: available_mechanical_displacements_index_from_node_index[part][node] with part...part_index, node...node_index will return the index of the first nodal dof. the other local dofs of the same node will follow in the global array, for example the index of the third local dof is (available_mechanical_displacements_index_from_node_index[part][node]+2)
