3. NATURE OF PHYSICAL PROBLEM SOLVED

GHT is a generalized heat conduction programme. This programme solves steady-state and/or transient heat conduction problems in three-dimensional geometry. Boundary temperatures and heat generation may be a function of positions and/or time. Material properties and film coefficients may be considered as a function of position but are assumed constant with respect to temperature and time.

4. METHOD OF SOLUTION

The method used in GHT is numerical integration  of the appropriate finite-difference equations.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The number of nodal points is limited to 950, which includes internal and boundary points. All boundary points, however, which have the same temperature-time relationship may be considered as one point. The number of neighbours which may affect a given point must be equal to or less than 8.
