TOPA2D is a two- dimensional implicit finite element computer codes for heat transfer analysis. TOPAZ2D can also be used to solve electrostatic and magnetostatic problems. The program solves for the steady-state or transient temperature or electrostatic and magnetostatic potential field on two-dimensional planar or axisymmetric geometries. Material properties may be temperature- or potential-dependent and either isotropic or orthotropic. A variety of time- and temperature- dependent boundary conditions can be specified including temperature, flux, convection, and radiation. By implementing the user subroutine feature, users can model chemical reaction kinetics and allow for any type of functional representation of boundary conditions and internal heat generation. The program can solve problems of diffuse and specular band radiation in an enclosure coupled with conduction in the material surrounding the enclosure. Additional features include thermal contact resistance across an interface, bulk fluids, phase change, and energy balances.

Thermal stresses can be calculated using the solid mechanics code NIKE2D (NESC 9923), which reads the temperature state data calculated by TOPAZ. No general mesh generation capability is provided. Rows of evenly spaced nodes and rows of sequential elements may be generated. For complex zoning, the mesh generation code and preprocessor, MAZE (NESC 9907), should be used. The ORION (NESC 9906) interactive postprocessor can be used to produce temperature contour, flux contour, various geometry and temperature-time history plots, and plots of temperature vs. distance along arbitrary cut lines. TOPAZ3D (NESC 9599) is a three- dimensional implicit finite element code for heat transfer analysis.

The TOPAZ2D CRAY1, DEC VAX11 version source is operable on the DEC VAX-11 computer, as supplied. The CRAY1 computer version can be generated by enabling those source records with the identifier 'CRAY1' in columns 73-77 and disabling, or commenting out, those with the 'VAX' identifier in the columns 73-75.
