!(((((((((((((((( Purpose of the routine ))))))))))))))))))))))))))))))))))))))
!------------------------------------------------------------------------------|
! this routine finds all nodes that are completely in the void by this I mean
! that they are not connected by any element to a node that is not in the void
! those nodes are given a vo%node=1 flag; all others have vo%node=0
! there are vo%nnode nodes that are not in the void
! it also calculates the nodes that are in the fluid vo%influid=.true.
! it also caculates the number of elements (vo%nleaves) and
! bad faces (vo%nface) that are not in the void
! and corresponding flag arrays vo%leaf and vo%flace
! finally it computes two "correspondence" arrays that tell us the connection
! between dofs in the global set and dofs in the subset that is not in the void
! nleaves is the number of leaves/fe
! nface is the number of bad faces
! nnode is the number of nodes
! icon is the element-node connectivity matrix
! iface is the bad face connectivity matrix
! mpe is the number of nodes per elements
! vo is the structure containing the information on where the void is
! it is constructed in this routine
! lsf contains the nodal values of the nlsf level set functions
! materialn contains the material number associated to each lsf
! the algorithms in this routine are quite straightforward
! and based on the value of the first (zeroth) lsf
