Computational mesh modification
Change mesh set up in the following way
Modify file system/blockMeshDict.m4:
// Hub radius
define(r, 0.2)
// Impeller-tip radius
define(rb, 0.5)
// Baffle-tip radius
define(Rb, 0.7)
// Tank radius
define(R, 1)
// MRF region radius
define(ri, calc(0.5*(rb + Rb)))
// Thickness of 2D slab
define(z, 3.0)
// Base z
define(Zb, 0)
// Top z
define(Zt, calc(Zb + z))
// Number of cells radially between hub and impeller tip
define(Nr, 6)
// Number of cells radially in each of the two regions between
// impeller and baffle tips
define(Ni, 2)
// Number of cells radially between baffle tip and tank
define(NR, 6)
// Number of cells azimuthally in each of the 8 blocks
define(Na, 4)
// Number of cells in the thickness of the slab
define(Nz, 10)
