eta/DYNAFORM Application Manual


The eta/DYNAFORM software package consists of four programs. These
programs represent the pre-processor, solver and post-processor. They are:
eta/DYNAFORM, eta/Job Submit, eta/POST and eta/3DPlayer.
eta/DYNAFORM is the pre-processor portion of the software package. Sheet metal
forming models are constructed using this software. It includes VDA and IGES
translators for importing line data and a complete array of tools for altering or
constructing line data and meshing it.
LS-DYNA is the software package’s solver. eta/DYNAFORM has a complete
LS-DYNA interface allowing the user to run LS-DYNA from eta/DYNAFORM.
eta/POST and eta/GRAPH are the post-processing portions of the package. These
programs are used to post-process the LS-DYNA result files from the analysis.
eta/POST creates contour, deformation, FLD, and stress plots and animations with
the result files. eta/GRAPH contains functions for graphically interpreting the
same results.
