/*! \brief DYNA Files Reader
|
|
|
|
This Function will read in a DYNA file, designated by inputname. Only three Information will be parsed:-
|
|
*NODE, *CONSTRAINTS_ADAPTIVITY, and *ELEMENT_SHELL_THICKNESS (for the third, only first line will be parsed)
|
|
|
|
From *NODE the coordinates and vertex index will be parsed. From *ELEMENT_SHELL_THICKNESS only the face nodal
|
|
will be parsed, and from *CONSTRAINTS_ADAPTIVITY the constraints point (flagged by Constrain and Constrained) will
|
|
be parsed.
|
|
|
|
As output, a mesh.
|
|
|
|
TODO:-
|
|
1. A face might consists of 2 opposite constraint points, 3 constraint points or 4 constraint points in it's
|
|
edges. These are not implemented yet.
|
|
2. Some other keyword might contain the face information other than *ELEMENT_SHELL_THICKNESS
|
|
3. Multiple-PIDS DYNA files is not yet implemented. This program still assumes that it's only a single PID DYNA
