C #####################################################################
c
c   FORMAT:
c
c   MASSAGE / BISECTION_LENGTH / MERGE_LENGTH / TOLDAMAGE / TOLROUGHNESS
c      ifirst,ilast,istride / [nosmooth,norecon,strictmergelength,ignoremats,
c      lite,checkaxy,semiexclusive,exclusive]
c
c   MASSAGE creates, annihilates, and moves nodes and swaps
c   connections in a 2D or 3D mesh in order to improve
c   element aspect ratios and establish user-desired edge
c   lengths.
c
c   Specifically, MASSAGE performs up to four iterations of
c   a loop which calls AGD3D (a routine for automated merging
c   of nodes), RECON (a routine for automated reconnection
c   of edges), and SGD (a routine for element aspect ratio
c   improvement using smoothing).  MASSAGE then calls
c   CEL_CHAIN which performs Rivara edge refinement and
c   then another call to RECON.  In the case of 2-D surface grids,
c   this is then followed by a call
c   to CER_CHAIN which is another edge refinement routine and
c   then a final call to RECON if necessary.
c
c   AGD3D will attempt to merge edges that are shorter than
c   MERGE_LENGTH.  CEL_CHAIN will attempt to bisect edges
c   that are longer than BISECTION_LENGTH.  For 2-D surface grids,
c   CER_CHAIN will attempt
c   to bisect edges that deviate from an averaged surface normal
c   ("have a roughness of") greater than TOLROUGHNESS.  RECON will attempt
c   to create 'nice' elements by using face swapping.  (The
c   value of the LaGriT IVORONOI parameter determines the
c   meaning of 'nice'.)  SGD will attempt to improve element
c   aspect ratios by moving nodes.
c
c   To ensure that the actions of AGD3D, RECON, and
c   SGD are controlled and harmonious, the parameter
c   TOLDAMAGE exists, and there are guidelines for choosing the
c   relative values of BISECTION_LENGTH, MERGE_LENGTH,
c   TOLDAMAGE, and TOLROUGHNESS.
c
c   TOLDAMAGE is a parameter which controls how much the grid
c   will be deformed by AGD3D, CEL_CHAIN, RECON, and SGD.
c   The 'damage' is a measure of how much interfaces and
c   external boundaries are deformed.  Roughly, it measures
c   the depths of 'dents' that are invariably introduced when
c   nodes are moved, annihilated, and faces are swapped.
c   We guarantee that the damage of any single node movement,
c   node annihilation, or face swap is bounded by TOLDAMAGE.
c   So if TOLDAMAGE is set to an extremely small number, one
c   can expect hardly any node movements, annihilations, or
c   face swaps will be allowed.  Conversely, if TOLDAMAGE is
c   set too large, physical interfaces may be significantly
c   deformed by the action of MASSAGE.  Experience has
c   shown that setting TOLDAMAGE equal to approximately
c   .01 times the diameter of the mesh frequently gives
c   acceptable results.
c
c   The guidelines for selecting BISECTION_LENGTH, MERGE_LENGTH,
c   TOLDAMAGE, and TOLROUGHNESS are as follows.  BISECTION_LENGTH should not be
c   smaller than MERGE_LENGTH, or the action of merging nodes
c   together will be largely pointless because the newer, longer
c   edges created by merging will simply be bisected again.
c   In fact, merging all edges of length > MERGE_LENGTH together
c   can easily create edges of length roughly 3*MERGE_LENGTH in the mesh.
c   Hence it is recommended that BISECTION_LENGTH be at least
c   three times as large as merge length.
c
c   Merges of edges of length <= MERGE_LENGTH are meant to
c   coarsen the mesh, but are not meant to deform surfaces
c   and material interfaces on this scale.  The amount of
c   material/surface deformation (TOLROUGHNESS) is meant to be considerably
c   less than MERGE_LENGTH.
c
c   On the other hand, the maximum roughness tolerated in the graph
c   (TOLROUGHNESS) should be considerably more than TOLDAMAGE, or
c   roughness refinement will be triggered by actions such as
c   flipping or merging.
c
c   Hence, our guidelines for selecting these three parameters
c   are
c
c   BISECTION_LENGTH >= 3*MERGE_LENGTH >> TOLDAMAGE.
c
c                          AND
c
c   TOLROUGHNESS >= 10*TOLDMAMAGE  (for 2-D surface grids).
c
c   For example, for a grid with diameter of order three,
c   we have used
c
c   BISECTION_LENGTH, MERGE_LENGTH, TOLDAMAGE, TOLROUGHNESS =.3, .1, .01, .1
c
c   If one of {BISECTION_LENGTH, MERGE_LENGTH} are omitted, the omitted
c   one will be set so that BISECTION_LENGTH=3*MERGE_LENGTH.  If they are
c   both omitted, they will both be taken to be infinity.
c   If TOLDAMAGE is not specified, no node annihilation will take place.
c   IF TOLROUGHNESS is not specified, no refinement on roughness will
c   occur and thus the format is compatible with old decks where
c   refinement on roughness did not occur.
c
c   The final, optional arguments can be one or more of
c   SMOOTH (the default), NOSMOOTH,NORECON,
c   LITE, IGNOREMATS, STRICTMERGELENGTH, CHECKAXY, SEMIEXCLUSIVE, and EXCLUSIVE.
c   NOSMOOTH causes MASSAGE to deviate from the above
c   description, in that node smoothing by SGD is not performed.
c   Smoothing as described above is performed when SMOOTH is specified.
c   The optional argument STRICTMERGELENGTH forces strict interpretation
c   of MERGE_LENGTH so that there is no merging along the edges of flat
c   elements.  This is important if IGNOREMATS is specified to avoid losing the interfaces.
c   The optional argument IGNOREMATS causes massage to process the a
c   mulitmaterial mesh in a single material mode; it ignores the material interfaces.
c   If LITE is specified, only one iteration of the merging/reconnection
c   loop is executed, and a reconnection after edge refinement is
c   omitted.  This is suitable for applications, such as Gradient
c   Weighted Moving Finite Elements, where MASSAGE is called repeatedly.
c   If CHECKAXY is given, then we insure that for 2D meshes,
c   the output mesh will have positive xy-projected triangle areas,
c   provided that the input mesh had them in the first place.
c   If EXCLUSIVE is given, then edge refinement operations will only
c   be performed on edges whose endpoints are BOTH in the PSET that
c   MASSAGE is working on.  (As usual, new nodes created by refinement
c   are added to the PSET so that massage can refine edges recursively.)
c   The default behavior is 'inclusive', where only ONE edge endpoint
c   has to belong to the PSET for the edge to be eligible for refinement.
c   If SEMIEXLUSIVE is given, refinement will only be triggered by
c   edges with both endpoints in the PSET, but some edges with less than
c   two endpoints in the PSET might be refined as part of a
c   'Rivara chain' triggered by the refinement of an edge with both
c   endpoints in the PSET.  This represents an intermediate case between
c   INCLUSIVE and EXCLUSIVE.
c
c   Note:  Since CEL_CHAIN is called only once at the end of MASSAGE,
c   it may be necessary to call MASSAGE twice for optimal results.  This
c   is because annihilation of nodes is done with an intent to improve
c   element aspect ratios, but cannot be effective if there are too
c   few nodes initially.
c
c   Note: The user may wish to issue a "RMPOINT/COMPRESS" after MASSAGE
c   operations that merge a significant number of nodes.
c
c   EXAMPLES:
c
c   massage /0.3/0.1/0.01/
c      Mesh edges longer than 0.3 will be bisected; mesh edges shorter than 0.1
c      might be collapsed if that causes damage (normal surface motion) to material
c      interfaces or external boundaries less than 0.01 ; smoothing of nodes
c      causing damage less than 0.01 is allowed ; face swapping causing damage
c      less than 0.01 is allowed.
c
c   massage /0.3/0.1/0.01/0.1/
c      Same as above but for 2-D surface meshes, roughness greater than
c      0.1 will trigger refinement.
c
c   massage /0.3/0.1/0.01/pset,get,PSET1
c      Mesh edges (containing at least one endpoint in PSET1) longer than 0.3
c      will be bisected; mesh edges shorter than 0.1 might be collapsed if that
c      causes damage (normal surface motion) to material interfaces or external
c      boundaries less than 0.01 and if the annihilated node is in PSET1;
c      smoothing of nodes in PSET1 causing damage less than 0.01 is allowed;
c      face swapping causing damage less than 0.01 is allowed (unfortunately,
c      LaGriT at this time does not restrict swapping to PSET1).
c
c   massage /0.3/0.1/0.01/pset,get,PSET1/nosmooth
c      As above, but without smoothing.
c
c   massage /1.e+20/0.1/0.1/1,0,0/nosmooth
c      Because of the virtually infinite value of BISECTION_LENGTH, no edges
c      will be bisected.  Since MERGE_LENGTH=TOLDAMAGE=0.1, merging of edges
c      of length less than 0.1 will be considered, and will not be rejected
c      because of excessive damage.  Hence we expect that all edges of length
c      less than 0.1 will be merged away (except in those cases where merging
c      would invert tetrahedra or change material topology).   Because
c      NOSMOOTH is specified, no smoothing will take place.  Face swapping
c      causing damage less than TOLDAMAGE is allowed.
c
c   massage/1.e+20/1.e-9/1.e-9/1,0,0/nosmooth/strictmergelength/ignoremats
c      This set of arguments will remove degenerate elements from a mesh
c      by merging nodes that have the same coordinate values ( within 1.e-9).
