SPRNT

=====

SPRNT is a river dynamics simulation software package. Technically it is a fully dynamic Saint Venant Equation solver. Quite a few nice techniques are developed to make SPRNT not only fast but also capable of handling large networks. The code is mainly written by Dr. Frank Liu at IBM Research, as the result of academic collaborations with Professor Ben Hodges in the Civil Engineering Department of University of Texas at Austin. It is released under Eclipse Public License. IBM owns the copyright.

Content:

• src/ directory contains the core SPRNT routine source code
• spt/ contains the code of a front-end to run SPRNT as command-line
• examples/ contains several netlist examples
• demo/ contains an example on how to run SPRNT through API
• doc/ contains a user's manual on the syntax of the netlist
• ThirdParty/ contains modules to build solver library as dynamic-linked library

Install

See INSTALL on how to build and install the software
