In this work, the parallel property of pressure equation solver with variable order multigrid method is presented. For improving the parallel efficiency, the restriction of processor elements (PEs) on coarser multigrid level is considered. The results show that the parallel property with restriction of PEs can be about 10% higher than one without restriction of PEs. The present approach ...
