Reading in models from disk.

PRIMER's native internal data structures are based on Ansys LS-DYNA keyword format, with some additions for specialist purposes.

Files may be read in a variety of formats, some of which require a considerable degree of translation to convert them to PRIMER internal data.

List of File Formats Read by PRIMER summarises what is read and how it is converted: more details of format conversions are given in Appendix F .

In the example a. Ansys LS-DYNA keyword file is to be read into model #1 (which is the first free model number).

Compressed and binary Ansys LS-DYNA input files

Ansys LS-DYNA files that are compressed in .gz and .zip format may be read and written directly. In addition a new proprietary binary format that is both more compact and gives faster i/o may be used, see Appendix F for more details. PRIMER can also read .zip archives that are encrypted.
