anjantula is on a distinguished road
I am working as an RA , i am working on simulation of flaring stacks . yesterday i made a small 2d geometry to test my mechanism results .

Reading "C:\Documents and Settings\Anjan\jan22-1.msh"...
32361 nodes.
200 mixed symmetry faces, zone 3.
80 mixed velocity-inlet faces, zone 4.
40 mixed velocity-inlet faces, zone 5.
40 mixed wall faces, zone 6.
200 mixed pressure-outlet faces, zone 7.
160 mixed pressure-outlet faces, zone 8.
63640 mixed interior faces, zone 10.
32000 quadrilateral cells, zone 2.

shell conduction zones,

Grid Check

Domain Extents:
x-coordinate: min (m) = 0.000000e+000, max (m) = 1.000000e+000
y-coordinate: min (m) = 0.000000e+000, max (m) = 5.000000e+000
Volume statistics:
minimum volume (m3): 1.637497e-006
maximum volume (m3): 5.801886e-004
total volume (m3): 5.000000e+000
Face area statistics:
minimum face area (m2): 4.999992e-005
maximum face area (m2): 2.523024e-002
Checking number of nodes per cell.

Checking right-handed cells.
Checking face handedness.
Checking face node order.

Checking boundary types:
Checking face pairs.
Checking periodic boundaries.
Checking node count.
Checking nosolve cell count.
Checking nosolve face count.
Checking face children.
Checking cell children.
Checking storage.

But after giving all the condition and iterating it giving errors like

cell id =xxxx with cell centriod ( xx,xx) failed
cell id =xxxx with cell centriod ( xx,xx) failed
cell id =xxxx with cell centriod ( xx,xx) failed
cell id =xxxx with cell centriod ( xx,xx) failed
cell id =xxxx with cell centriod ( xx,xx) failed

total no of cells failed = 40
iteration 2

and the same story

please help me on this error
