Introduction to LS-PrePost

LS-DYNA models can be generated and modified with the pre and post processor LS-PrePost. The program might be used to visualize the results of the LS-DYNA  Finite-Element analysis. LS-DYNA input files can be read in and editing of the keyword cards in the graphical user interface is possible. The capabilities of LS-PrePost have been developed constantly over the past years. Especially in the range of pre-processing many new features have been added.

In this one day seminar the application of LS-PrePost is demonstrated. The goal is to explain as possible complete all the special features and all the menu items of the graphical user interface focused on practical applications.
