Detailed Description

Read LS-Dyna databases (d3plot)

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.

Attention
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.

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.

Open Issues
:
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).

Open Issues
: 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.

These functions should only be called from within RequestData() since they require the various output meshes to exist.

virtual void vtkLSDynaReader::ResetPartInfo ( )

protectedvirtual

Resets the Part information to the default state

virtual int vtkLSDynaReader::ReadInputDeck ( )

protectedvirtual

Called from within ReadHeaderInformation() to read part names associated with material IDs.

virtual int vtkLSDynaReader::ReadPartTitlesFromRootFile ( )

protectedvirtual

Called from within ReadHeaderInformation to read part names from the end of the first d3plot file. Used if ReadInputDeck fails.

virtual int vtkLSDynaReader::ReadUserMaterialIds ( )

protectedvirtual

Called from within ReadHeaderInformation() to read arbitrary material IDs (if present) or manufacture sequential material IDs (if not present).

int vtkLSDynaReader::ReadInputDeckXML ( ifstream & deck )

protected

ReadInputDeck determines the type of file (keyword or XML summary) and calls one of these two routines to read the file.

int vtkLSDynaReader::ReadInputDeckKeywords ( ifstream & deck )

protected

ReadInputDeck determines the type of file (keyword or XML summary) and calls one of these two routines to read the file.

int vtkLSDynaReader::WriteInputDeckSummary ( const char * fname )

protected

ReadInputDeckKeywords calls this function if it was successful in reading part names for materials.

virtual void vtkLSDynaReader::ReadDeletionArray	(	vtkUnsignedCharArray *	arr,
		const int &	pos,
		const int &	size
	)

protectedvirtual

Read an array of deletion data. This is used by ReadDeletion to actually read the data from the file (as opposed to attach it to the proper place in the VTK dataset) depending on the value of "MDLOPT". The array passed to this routine is filled with ones if deleted, zero it is not deleted The number of tuples must be set on the array previous to calling this routine. Note: pos is the position in the size that the death value is store at

virtual void vtkLSDynaReader::ReadCellProperties	(	const int &	type,
		const int &	numTuples
	)

protectedvirtual

Read all the cell properties of a given part type

void vtkLSDynaReader::ResetPartsCache ( )
