ASCEND modelling environment

The ASCEND project at Carnegie Mellon University

ASCEND is a flexible modelling environment for solving hard engineering and science problems. It offers:

  • an object-oriented model description language for describing your system,
  • an interactive user interface that allows you to solve your model and explore the effect of changing the model parameters, and
  • a scripting environment that allows you to automate your more complex simulation problems.

ASCEND was originally written at Carnegie Mellon University in the 1980s and includes powerful and reliable solver routines that analyse the structure of your model and can solve thousands of simultaneous nonlinear equations in a few seconds on everyday computer hardware. It is under active development and is licensed under the GNU General Public License ensuring that it is free software and will remain free.

Getting ASCEND

ASCEND is free software, licensed under the GNU General Public License. Our last 'stable' release was back in 2000. See also our old download page.

Documentation

The ASCEND documentation is gradually being migrated from to a new format. The details are on the wiki. Currently, the documentation is not shipped as part of the binary packages for ASCEND.

Participate

ASCEND is currently research-quality software and contributions from users are very much encouraged. All the details are in the ASCEND Development Wiki. If you have a hard problem that you can't solve with ASCEND, please let is know! You might also want to submit bug reports or contact the developers.
