3. DESCRIPTION OF PROGRAM OR FUNCTION

DOT-BPMD is a general-purpose,  finite-element, heat-transfer program used to predict thermal environments. The code considers linear and nonlinear transient or steady-state heat conduction in two-dimensional planar or axisymmetric representations of structures. Capabilities are provided for modeling anisotropic heterogeneous materials with temperature-dependent thermal properties and time-dependent temperature, heat flux, convection and radiation boundary conditions, together with time-dependent internal heat generation.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Limitations include  the lack of a three-dimensional analysis capability, no radiative or convective internal heat transfer, and the need to maintain a constant time-step in each program execution.

6. TYPICAL RUNNING TIME:
NESC9833/01
NEA-DB executed the test cases included in this package on a CDC CYBER 740 computer. Required CPU times varied from 0.4 to 1477 seconds depending on the case.

7. UNUSUAL FEATURES OF THE PROGRAM

Strengths of DOT-BPMD include its  ability to account for a wide range of possible boundary conditions, nonlinear material properties, and its efficient equation solution algorithm.

8. RELATED AND AUXILIARY PROGRAMS

DOT-BPMD may be used in the evaluation of steady-state geothermal gradients as well as in the transient heat conduction analysis of repository and waste package subsystems. It may also be used to generate temperature distributions to be used as input to the SCEPTER thermomechanical codes VISCOT (NESC Summary R9846), MATLOC (NESC R9851), and UTAH2 (NESC Summary R9848). In the analysis of the waste package, DOT-BPMD can be used to calculate temperatures for input to the WAPPA, waste package performance assessment program.
