// .NAME vtkLSDynaReader - Read LS-Dyna databases (d3plot)
// .SECTION Description
// This filter reads LS-Dyna databases.
//
// The Set/GetFileName() routines are actually wrappers around the
// Set/GetDatabaseDirectory() members; the actual filename you choose is
// irrelevant -- only the directory name is used.  This is done in order to
// accommodate ParaView.
//
// Note that this reader produces 7 output meshes.
// These meshes are required as several attributes are defined on subsets
// of the mesh.  Below is a list of meshes in the order they are output and
// an explanation of which attributes are unique to each mesh:
// - solid (3D) elements: number of integration points are different than 2D
// - thick shell elements: number of integration points are different than 
// planar 2D
// - shell (2D) elements: number of integration points are different than 3D
// - rigid surfaces: can't have deflection, only velocity, accel, etc.
// - road surfaces: have only a "segment ID" (serves as material ID) and a 
// velocity.
// - beam elements: have Frenet (TNB) frame and cross-section attributes 
// (shape and size)
// - spherical particle hydrodynamics (SPH) elements: have a radius of 
// influence, internal energy, etc.
// Because each mesh has its own cell attributes, the vtkLSDynaReader has a
// rather large API.  Instead of a single set of routines to query and set
// cell array names and status, one exists for each possible output mesh.
// Also, GetNumberOfCells() will return the sum of all the cells in all 7
// meshes.  If you want the number of cells in a specific mesh, there are
// separate routines for each mesh type.
//
// .SECTION "Developer Notes"

// LSDyna files contain 3 different types of sections: control, data, and
// state.  Control sections contain constants that describe the type of
// simulation data in a file or group of files.  Data sections contain
// simulation information that is invariant across individual time steps
// (but can vary when a mesh adaptation occurs).  This information includes
// material, connectivity, and undeformed geometry.  Finally, state data is
// information that varies with each time step.  Unless a mesh adaptation
// occurs, there will be a single control and data section, and they will
// be located at the start of the database (the first file).
// 
// In their infinite wisdom, LSDyna developers decided to split simulation
// data into multiple files, each no larger than some predetermined limit.
// Each file can contain one section, a partial section (if it would not
// fit into a single file), or multiple sections. Files are padded with
// zeros so that their lengths will be multiples of 512*512.  The size of
// each section is determined by constants in the control and data
// sections, which means that these must be parsed carefully in order to
// correctly locate desired information.  Unfortunately, the constants are
// not terribly well-documented and in some cases the documentation is in
// error.
//
// .SECTION "Open Issues"
// The LS-Dyna file format document leaves a good bit open to
// interpretation.  In addition to the "documentation vs. files in the
// wild" issues there are also implementation problems.
//
// - Where exactly may breaks to a new file occur in the pre-state 
// information? At each section?
// - Will state data sections (node/cell data, element deletion, sph data, 
// rigid body motion) be moved to  the beginning of a new file if their data 
// will be too large for a given file, or are all the sections
// counted together as a single state (makes more sense for keeping time 
// word at start of every file).
//  The questions above arise because the docs (p. 3) state "There are 3
// sections in this database." but then call many smaller pieces of data
// "sections". Should they be subsections? The docs are quiet about whether
// the second section (of 3) is ever split across multiple files and, if
// so, whether it is done at (sub)section boundaries when possible or just
// wherever it needs to occur.
// - How many components does Eddy Viscosity have? It's shown as 7 bits in 
// NCFDV1 which makes no sense at all.
// - Why is NARBS larger than 10+NUMNP+NEL8+NEL2+NEL4+NELT (which is the 
// value specified by the documentation)?
// Obviously, NARBS is definitive, but what are the extra numbers at the end?
// - Is there a difference between rigid body elements NUMRBE and rigid road 
// surfaces? It appears that the nodes and connectivity of the road surface 
// are given separately (p.13) while on p.7 the Material
//   Type Data subsection says that shells in a rigid body will just have a 
// certain material ID but be  interspersed among deformable shell elements.
// - Word 37 of the control section serves two possible purposes... it can 
// mean NMSPH or EDLOPT.
//   I assume that different versions of the code use that word differently. 
// How do we know the difference?
// - It's unclear how much state isn't stored when a shell element is marked 
// as rigid. Specifically, is element deletion data stored for rigid shells? 
// Page 21 of the spec is mute on this.
// - The loop to read cell User IDs won't work if Rigid Body and Shell 
// elements are interleaved (which I now believe they are).
//
// On the VTK side of things:
// - Berk has nudged me towards multiblock outputs but hasn't committed to 
// exactly how things can be made efficient for a parallel version of the 
// reader.
// - This reader will eventually need to respond to a second output port for 
// "small spatial, large temporal" queries.
// - The reader doesn't handle crack files (d3crck)
// - The reader doesn't handle interface force files (no default name)
// - The reader doesn't handle time history (abbreviated output) files (d3thdt)
// - The reader doesn't handle dynamic relaxation files (d3drfl)
// - The reader doesn't handle reduced parts (state for a subset of parts) files (d3part)
// - The reader doesn't handle mode shape files (d3eigv)
// - The reader doesn't handle equilibrium iteration files (d3iter)
// - The reader doesn't handle extra time data files (d3xtf)
// - The reader doesn't handle printer files (d3hsp)
// - The reader doesn't handle modal neutral files (d3mnf)
// - The reader doesn't handle packed connectivity.
// - The reader doesn't handle adapted element parent lists (but the 2002 specification says LSDyna doesn't implement it).
// - All the sample datasets have MATTYP = 0. Need something to test MATTYP = 1.
// - I have no test datasets with rigid body and/or road surfaces, so the 
// implementation is half-baked.
// - It's unclear how some of the data should be presented. Although blindly 
// tacking the numbers into a large chuck of cell data is better than nothing,
// some attributes (e.g., forces & moments) lend themselves to more elaborate
// presentation. Also, shell and thick shell elements have stresses that 
// belong to a particular side of an element or have a finite thickness that 
// could be rendered.
//   Finally, beam elements have cross sections that could be rendered. 
// Some of these operations require numerical processing of the results and 
// so we shouldn't eliminate the ability to get at the raw simulation data. 
// Perhaps a filter could be applied to "fancify" the geometry.
