use prec, only: pReal,pInt

! ---------------------------
! _Nelems : total number of elements in mesh
! _NcpElems : total number of CP elements in mesh
! _Nnodes : total number of nodes in mesh
! _maxNnodes : max number of nodes in any CP element
! _maxNips : max number of IPs in any CP element
! _maxNipNeighbors : max number of IP neighbors in any CP element
! _maxNsharedElems : max number of CP elements sharing a node
!
! _element : FEid, type, material, texture, node indices
! _node : x,y,z coordinates (initially!)
! _sharedElem : entryCount and list of elements containing node
!
! _mapFEtoCPelem : [sorted FEid, corresponding CPid]
! _mapFEtoCPnode : [sorted FEid, corresponding CPid]
!
! MISSING: these definitions should actually reside in the
! FE-solver specific part (different for MARC/ABAQUS)..!
! Hence, I suggest to prefix with "FE_"
!
! _mapElementtype : map MARC/ABAQUS elemtype to 1-maxN
!
! _Nnodes : # nodes in a specific type of element
! _Nips : # IPs in a specific type of element
! _NipNeighbors : # IP neighbors in a specific type of element
! _ipNeighbor : +x,-x,+y,-y,+z,-z list of intra-element IPs and
! (negative) neighbor faces per own IP in a specific type of element
! _NfaceNodes : # nodes per face in a specific type of element
! _nodeOnFace : list of node indices on each face of a specific type of element
! _ipAtNode : map node index to IP index in a specific type of element
! _nodeAtIP : map IP index to node index in a specific type of element
! _ipNeighborhood : 6 or less neighboring IPs as [element_num, IP_index]
! order is +x,-x,+y,-y,+z,-z but meaning strongly depends on Elemtype
