ODEcalc for Windows: An Ordinary Differential Equation (ODE) Calculator! State your equation and boundary or initial value conditions and it solves your problem. Plots solution y and derivative ydot versus x.

Solves most Boundary Value Problems (BVP) and Initial Value Problems (IVP) for Nth order ODE. ODE may be non-linear, implicit, and any order. Source code included ... it's short! Great teaching tool! Helps students understand difference in BVP and IVP plus their importance in solving practical ODEs. ODE and algebraic system of equations may be solved using the methodology in this demo.

Hardcopy prints in Windows is now available.

This is a Fortran Calculus demo application.

An Ordinary Differential Equation (ODE) Calculator! State your equation with boundary or initial value conditions and ODEcalc will solve your problem. Plots solution (y) and derivative (ydot) versus x. Solves most Boundary Value Problems (BVP) & Initial Value Problems (IVP) for any order ODE. ODE may be non-linear, implicit, and any order. Source code included ... it's short! ODEcalc helps one understand difference in BVP & IVP and their importance in solving practical differential equations. PDEs, ODEs and algebraic system of equations may be solved using the methodology in this demo. Great for learning BVP & IVP solution techniques. Solvers used are based on Automatic Differential (AD) and Operator Overload techniques.

ODEcalc was made possible due to a Calculus compiler. The source code (ODE4user.fc) file is included in order to show the Calculus programming simplicity. ODEcalc was written to show that differential equations are solved without numerical algorithms from the user. Differential equation problems are solved with little code other than ones equations. One initial value problem required only 19 lines of code in order to be solved!
