 May 22, 2002, 11:10 A newby asking for advice on stirred tank simulati #1 J. H. Fan Guest   Posts: n/a I want to compute the 3d flow field in stirred tank using sliding grid method. It is known to me that phoecnis offers two solution algorithm CCM and GCV. But I do not know the difference between them. Please give some advice which one is more suitable

The same can be solved with CCM i.e on colocated grid possibly using Rhie Chow algorithm or something better. 3. Multi block grids are always solved on colocated grids either by MBFGV solver where there natural links or by GCV solver where there are both natural and unnatural links. 4. GCV solver also solves when there is sliding of multiblock grids in the theta direction. Anyone there to correct my understanding or add to it

But the point I care most about is whether CCM\MBFGM can solve sliding mesh robustly. As I see from lib case f220, the CCM solver give unrealistic velocity predictions around the link between rotating and resting block.
