============================================================ error message
Tile partition information for Grid 01: 0229x0146x0041 tiling: 024x024

INP_PAR - domain decomposition error in input script file for grid: 1
The domain partition parameter, NtileJ = 24
is incompatible with grid size, Mm = 146
because it yields too small tile, Jstr = 1 Jend = -4
Decrease partition parameter: NtileJ
