The PC computer programme written in Borland Pascal for Borland Delphi under Windows 98/NT performs the transient analysis of three-dimensional structures subjected to surface heat flux, convective and radiative heat transfer, internal heat generation and temperature boundary conditions. The non-linearity may be due to either temperature dependent material properties or non-linear boundary conditions. The program is applicable to structures comprised of one or more materials. It uses a Network of cubic or prismatic volume elements, finite-volume method and a very efficient predictor-corrector differential equation System solver for stiff Problems to facilitate consideration of non-linearity, Radiation heat transfer between triangular/square Areas, latent heat in the calculation of temperature in materials such as freezing of water into ice or humid concrete and convection heat transfer in flow through tubes and ducts. Colour graphics are represented in VGA on screen or can be printed using PostScript/PCL on colour/laser Printer or into a file. By worked examples the application area of the PC computer program INSTATCP is demonstrated.
