Abstract

A geometric conservation law should be considered on moving boundary problems in body-fitted coordinated grid system. In this paper, as moving grid problem, threedimensional unstructured mesh with add and eliminated grid system is dealt with. In using add and eliminated grid method, the unstructured moving grid finite volume method is adopted. In this case, a control volume is treated as four-dimensional spacetime unified domain. So, a procedure of calculation is relatively complicatedly, espacially, in the case of parallel computation. In this paper, parallelization with OpenMP of the computation is estimated.
