HALF ANALYTIC HALF NUMERIC MULTIGRID VIRTUAL BOUNDARY PARALLEL NUMERICAL MODEL OF INVERSE HEAT CONDUCTION PROBLEMS

摘要

The half analytic half numeric multigrid virtual boundary parallel numerical model is constructed by using invert heat transient equation. This numeric model has high speedup and high parallel efficient. In this paper, the invert heat transfer equation is discussed, and the formal exact solution is derived by using delta function. Meanwhile, the discrete multi-grid is set up according to the solution. At last, the virtual boundary parallel technique is also applied to this model.
