ModSim, Model simulator software, Version 1.0

ModSim is a tool designed to for the study of the dynamical properties of models in the field of population biology and ecology.  It is also useful in a wide range of other scientific disciplines where ordinary differential models are used, such as engineering, mechanics, economics, chemistry, etc. 

ModSim can be used by researchers and by students and instructors to supplement courses in dynamical systems or ordinary differential equations. It is a friendly tool that can be used by scientists who are not mathematicians but who would like to benefit from the power of modeling.  It is based on the simple principle of "write and play" - just write a model down and play with it and you can immediately see the results on the screen.  Thus ModSim is not only a scientific tool but also a fascinating toy, ideal for the purpose of teaching.

Some of the features of ModSim:
bulletA very compact and specialized program, it comes on a single floppy diskette.
bulletThe equations are written in a natural way - no need to learn a new language. Plotting a function can be as simple as entering "x = sin t".  More examples.
bulletDynamic visualization of the computations, watch the results as the computations are being performed.
bulletDesigned to solve systems with delays.
bulletHelp file.
bulletThe resulting graphics can be pasted into standard Windows programs such as MS Word.

Requirements: PC compatible with MS Win 3.x,95/98/NT, 2MB of disk space

Cost: $150 ($100 for a student version). Plus shipping costs.
