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.
