Freeware Listing: Differential Equations

Graphical user interface (GUI) is used to solve up to two ordinary differential equations (ODEs). Results can be plotted easily. Choose between MATLAB's ode45 (non-stiff solver) or ode15s (stiffer solver). This is primarily a teaching tool..

ALL-IN-ONE MULTI-PHYSICS FINITE ELEMENT MODELING

Ever wish there was a flexible system for solving all the partial differential
equation problems that come up in science and engineering, so you didn't have
to buy and learn a new software tool for each problem?

Well, now your wish has come true. FlexPDE is a scripted finite element
partial differential equations problem solving environment.

FlexPDE reads your partial differential equation system and problem domain
definition in a natural, easy to learn language, then constructs a finite
element mesh, solves the problem, and presents graphical output of the solution.

The program PEEI 4.0.0.0 calculates numerical solutions of systems of partial differential equations that have number of equations equal or greater of the number of unknown functions. This version 4.0.0.0 has the following improvements over the previous ones. Have been improved the GUI, the management of the execution and the execution itself. Was made available the choice between two different methods of resolution of the total system of equations, labeled "normal method" and "other method". The "normal method" is essentially the same of the previous versions, but have been improved its performance and its termination criterion.

This function solves the linear fractional-order differential equations (FODE) with constant coefficients. The short memory principle has not neen used here, so the length of input signal is limited to few hundred samples. The parameters of the FODE (in its standard form) are the inputs of this function and the output is the samples of the output signal versus time..

JPlotter provides you with a simple application built in Java, designed for plotting mathematical functions and differential equations.

It provides support for functions such as y=f(x,z), where z varies between two user-defined values. Additionally, it can determine the area between a function and the X axis or two functions.

Minsky is a handy and accessible instrument that enables the simulation of economics models defined in terms of couple ordinary differential equations.

The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.

Scientific tool/solver to solve “Single Variable Non-Linear First Order Ordinary Differential Equations”. The app is very useful for engineers, scientists, economists to study the behaviour of a non-linear system encountered in practical problems. The app computes the value of dependent variable at a given value of independent variable (with given initial values of dependent and independent variable).The relationship between dependent and independent can be visualized using the “Plot” function. The results along with the “Plot” can be sent to any e-mail id by using “Send e-mail” option.

Solves Heat Transfer BVP, IVP, IP problems. Source code + Output files are included. Calculus (level) Programming makes solving partial differential equations, ordinary differential equations and algebraic equations simple. You state the equations, initial conditions, & parameter values and leave the solving method to the compiler. Equations maybe nonLinear, implicit, any order, any degree and/or constrained. Our website introduces Calculus Programming. Our main point is simulating entire company processes, distribution systems, etc. with an eye on ones company goal. This is accomplished by nesting of simulation problems in one Complete simulation run.
