A visual object-oriented software application for heat transfer has been developed in Java programming language. With the help of Unified Modeling Language (UML), the project identified the software requirements, which were classified into four areas: heat transfer problem setup, heat transfer solver, display of solved parameters, and saving/retrieval of heat transfer models. The software application covered steady state one-dimensional conduction heat transfer for Cartesian, cylindrical and spherical coordinate systems with temperature, heat flux and convection boundary conditions. A model...
