floating point error!

saha2122 · August 10, 2010, 01:38

hi every body !
I made my geometery in gambit(2 part)! then I merged them, and read them in fluent! when I run this file I get only these, nothing else!!!

iter continuity x-velocity y-velocity z-velocity k epsilon time/iter
reversed flow in 1440 faces on pressure-outlet 11.
turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 64505 cells
1 1.0000e+00 2.2368e+04 1.1092e-07 4.1418e-01 9.2458e+08 9.6332e+16 0:19:56 299
reversed flow in 501 faces on pressure-outlet 4.
reversed flow in 203 faces on pressure-outlet 11.
turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 308949 cells
Error: Floating point error: invalid number
Error Object: ()

what is this error?????????? is there anybody to help me? please!
I look forward 4 ur answer dear.

check your boundary conditions and specify correct pressure, velocity values. You get floating point error when some number gets divided by zero durning your iterations. Hope it helps
