SPHgen

Fills a STL geometry with SPH particles output formatted according to LS-Dyna input file structure

Main Features

• Reads an STL
• Fills the geometry with SPH particles of desired size
• Outputs the SPH part of a fixed format input-file for LS-Dyna

The SPH part has the number 9 in the k-file.

It can be opened in LSprepost for model bulding. LS-PrePost is an advanced pre and post-processor that is delivered at no cost with LS-DYNA. LS-Dyna is written, sold and supported by Livermore Software Technology Corporation. LSprepost can be downloaded at:
