Assimulo 2.1

A package for solving ordinary differential equations and differential algebraic equations.

Assimulo is a Cython / Python based simulation package that allows for simulation of both ordinary differential equations (ODEs), f(t,y), and differential algebraic equations (DAEs), f(t,y,yd). It combines a variety of different solvers written in C, FORTRAN and Python via a common high-level interface.

Assimulo currently supports Explicit Euler, adaptive Runge-Kutta of order 4 and Runge-Kutta of order 4. It also wraps the popular SUNDIALS (https://computation.llnl.gov/casc/sundials/main.html) solvers CVode (for ODEs) and IDA (for DAEs). Ernst Hairer’s (http://www.unige.ch/~hairer/software.html) codes Radau5, Rodas and Dopri5 are also available.

The package requires Numpy, Scipy and Matplotlib and additionally for compiling from source, Cython 0.15 and Sundials 2.4 together with a C-compiler and a FORTRAN-compiler.
