// .NAME LSDynaMetaData - Read LS-Dyna databases (d3plot)
|
|
// .SECTION Description
|
|
// A class to hold metadata about a particular file (such as time steps,
|
|
// the start of state information for each time step, the number of
|
|
// adaptive remeshes, and the large collection of constants that determine
|
|
// the available attributes). It contains an LSDynaFamily instance.
