Solving Ordinary Differential Equations in Excel

Initial value problems

IVSOLVE is a powerful initial value problem solver based on implicit RADAU5, BDF and ADAMS adaptive algorithms and is suitable for stiff nonlinear problems. IVSOLVE solves both ordinary (ODE) and differential-algebraic (DAE) systems of equations, including implicit systems with coupled time derivatives.

Boundary value problems

BVSOLVE is a powerful boundary value problem solver based on the COLDAE collocation method with adaptive mesh refinement which is suitable for stiff nonlinear problems. BVSOLVE solves both ordinary (ODE) and differential-algebraic (DAE) systems of equations, and supports both end points and interior boundary conditions locations.
