The 1D Heat Transfer software is used to study one-dimensional heat transfer (steady and unsteady states). It can be used for the geometries: wall, Lx = width; long cylinder, Lx = length; sphere, Lx = R/3 - with value zero for the flux in the center - and semi-infinite wall, Lx must be greater than the studied position. The software simulates problems with constant and variable properties. The initial condition can depend from the position.

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.

Heat Transfer 3.00 offers you a great solution which can help you to solve Heat Transfer BVP, IVP, IP problems. Source code + Output files are included. Calculus (level) Programming makes solving partial differential equations, ordinary differential equations and algebraic equations simple. You state the equations, initial conditions, & parameter values and leave the solving method to the compiler. Equations maybe nonLinear, implicit, any order, any degree and/or constrained.
