Description

            FreeASM1 is a set of three Scilab scripts allowing the simulation of activated
sludge process using ASM1 equations:

- batch : single closed reactor
- pointsettler steady state : single open reactor coupled with a clarifier
(modeled by a pointsettler 0D model) with sludge recirculation, constant
influent and sludge withdrawal values
- pointsettler dynamic : single open reactor coupled with a clarifier (modeled
by a pointsettler 0D model) with sludge recirculation, influent and sludge
withdrawal values defined by text files (which can be automatically generated by
means of OpenOffice spreadsheets provided.

Thank you very much. There are for the moment two references for this work (conference
proceedings) :

hi Julien Laurent 
i m new for scilab so i need your help to solve some differential equations
1. dy/dx =e^-x with y=0for x=0
2 dy/dx + (e^-x)y=x^2
help me ....
