Fortran Calculus Solvable Math Models include:

• Differential Equations (ODEs & PDEs)
• Nonlinear equations
• Implicit equations
• Constrained equations

• Allows Rapid Prototyping
• Decouples Math Models from Algorithms
• Accelerates Problem "Understanding"
• Enabled by Automatic Differentiation

Most problems are solved in hours! Presently, a PDE must be converted to a system of ODEs then solved in a day or two. Code consists of ones equations and a dozen or so other lines. Try it you'll like it!
