LS-PrePost is an advanced pre- and post-processor and model editor from LSTC, preparing input data and processing the results from LS-DYNA analyses.


LS-PrePost specializes in importing, editing, and exporting LS-DYNA models based on keyword input files. It is included with LS-DYNA without extra cost. The latest versions feature a redesigned graphic user interface which maximizes the graphics area by intuitively grouping program functions into icon-based toolbars. LS-PrePost supports the latest OpenGL standards to provide fast rendering of fringe plots and animation results. In order to keep pace with enhancements to LS-DYNA, the software is under constant development. Since no license file is required, LS-PrePost can be easily installed onto any machine operated using Windows or Linux.
