Research into the implementation of multigrid on block-structured grids will be conducted. The major area of investigations is the intergrid boundaries, common to block-structured grids. The treatment of the boundary conditions is a crucial component in achieving efficient and accurate numerical schemes. Investigation into new ways of implementing the boundary conditions in a multigrid multiblock scheme is proposed here. Areas of investigation are data structure, interpolation and restriction operators and conservation across boundaries. The resulting new method will be implemented on shared-memory parallel computers to achieve high turn around times.

将对多重网格在块结构网格上的实现进行研究。主要的研究领域是网格间的边界，这是块结构网格的共同之处。边界条件的处理是实现高效、准确的数值格式的关键部分。对多重网格多块格式中边界条件的新实现方法进行了研究。研究领域包括数据结构、内插和限制运算符以及跨边界守恒。由此产生的新方法将在共享内存的并行计算机上实现，以实现更高的周转时间。
