A Heat Transfer problem is described with equations and shows a Calculus-level language used for solving this two point boundary value problem (BVP). The equations being solved may be Ordinary Differential Equations and/or partial differential equations of any order & degree. Equations maybe nonLinear, implicit, any order, any degree and/or constrained.
Automatic Differentiation (visit http://www.digitalCalculus.com/page/593538) coupled with OperaTor Overloading are the key ingredience for a Calculus-level programming language.
Our website introduces the Fortran Calculus language/compiler. The 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 run.
