LS-PREPOST

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

LS-PrePost is particularly capable of importing, editing and exporting LS-DYNA keyword files for generating LS-DYNA input files. The new graphical interface of LS-PrePost version 3.0 can be operated intuitively by the icons and tool bars. It supports the latest Open-GL standards to provide fast rendering for fringe plots and animation results.

LS-PrePost is constantly being further developed and new development trends can be incorporated quickly. The software can be installed quickly and can be implemented on every computer because no license is required. LS-PrePost is being offered free of charge by DYNAmore.

LS-Run

LS-Run is a new graphical control center to start LS-DYNA simulations with either SMP or MPP versions of LS-DYNA. It is included as of LS-PrePost release v4.3 or in the developer version and can be started via “File>Run LS-DYNA”.

Once LS-PrePost is closed, the LS-Run window will remain open for further job control.

Note that the installation of the standalone a version will automatically install MS-MPI such that users of Windows operating systems quickly get started using MPP versions of
LS-DYNA.
