CHIMP HIerarchical Modeling Program

About | Download | FAQ | Documentation | Authors | Help | Contact


CHIMP is a generic tool for the modeling of chemical phenomena. Eventually, chemical reaction modeling, molecular mechanics, and quantum mechanic modules will be implemented, along with an easy to use graphical-user interface (GUI). At present, CHIMP has the ability to perform dynamic Monte Carlo simulations on chemical reactions, in particular heterogeneous catalytic reactions.

Download: You can download the source code for version 0.1 from SourceForge.
1. What is CHIMP?
Well, CHIMP is not done yet, and it will eventually be much more than it is now. So it depends on who you ask and what you mean. One day CHIMP will (hopefully) serve all your chemistry modeling needs: reaction/reactor modeling, advanced molecular mechanics techniques, an entire suite of quantum mechanical methods, and anything else you can convince us to do (or do yourself).
2. What does CHIMP do?
Right now, CHIMP is capable of reading in a text description of a chemical reaction mechanism and integrate the species balance and reactor design equations using a fast kinetic Monte Carlo technique. These capabilities will be enhanced in the near future.
3. Does CHIMP have a GUI?
No, but we would be happy to accept one.
4. How much does CHIMP cost?
Luckily for you, CHIMP is released under the GNU General Public License, so it will always be freely available. That is, you can always download it off the internet for free. In addition, the GPL ensures that the source code is also always available, so you can poke around and find out what makes it tick, fix bugs, and improve it yourself. In fact, all software available at SourceForge is distributed under some Open Source license.
5. Under what platforms does CHIMP run?
CHIMP is being developed using GCC3 in the Linux programming environment. It is being written in ISO/ANSI C and C++, so it should compile and run on any machine with a standards compliant compiler (this is easy for C, not so easy for C++). If your systems does not have a native, standards compliant compiler, get the latest version of GCC. It is also best to use the GNU assembler gas because of the long symbol names g++ generates. See the GCC FAQ for details.

There is no formal documentation now. You can look at the examples in the test directory that comes with the source code. You can also email the maintainer.
