CFX multigrid
 
Hi,

If the cell number of one direction can't be divided by 2 without a reminder, how could CFX implement multigrid method for the simulation?

Thanks.

CFX actually uses algebraic multigrid, so all of the manipulation is done at the level of the coefficient matrices. No new grids are generated. The algorithm is highly proprietary so that's all the detail I can give you.
