AYER, 2-D Thermal Conduction by Finite Element Method

1 - Description of program or function: AYER is a finite element program which implicitly solves the general two-dimensional equation of thermal conduction for plane or axisymmetric bodies. AYER takes into account the effects of time (transient problems), in-plane anisotropic thermal conductivity, a three-dimensional velocity distribution, and interface thermal contact resistance. Geometry and material distributions are arbitrary, and input is via subroutines provided by the user. As a result, boundary conditions, material properties, velocity distributions, and internal power generation may be made functions of, e.g. time, temperature, location, and heat flux. 2 - Method of solution: The finite element method is used with the assumption of a linear temperature distribution in each basic triangular element. 3 - Restrictions on the complexity of the problem - Maxima of: 1000 nodes, 50 materials, 50 boundaries, 6 sides/element. The nodes, materials, and boundaries maxima are set in DIMENSION statements and can be adjusted
