itermd

For simulations or modeling studies of regulations, Automation or various phenomena, with parameters that may be random, interdependent variables without simple rules, etc..
It can also be used to study mathematical curves remarkable how 'pragmatic'.

The claim of these tools is to facilitate the programming of simulations by providing routines to quickly generate:
-display windows and input parameters
-help to display the variation in the data as graphs
-management of iterations
Goal for the user: quickly programme his simulation.

Requires knowledge of C language.
Knowledge of gtk and cairo (for simple graphs) is not necessary.

See examples.
-sugar fermentation kinetics
-parachute drop
-cycle of a water tank heated by solar panels
-curve of chase

For your simulation, simply copy and adapt some lines corresponding explicit examples.
