Hello folks,

I have the problem after solving one time step in a CFX-Simulation:
+--------------------------------------------------------------------+
| ERROR #002100004 has occurred in subroutine Out_Scales_Flu. |
| Message: |
| The Reynolds number is outside of the range expected based on the |
| Option selected for the TURBULENCE MODEL. Check this setting, |
| the values of the properties, mesh scale, consistency of units |
| and solution values in the input file. Execution will proceed. |
+--------------------------------------------------------------------

As posted below, the Reynolds-Number equals Zero.

"Reynolds Number = 0.0000E+00"

Does someone know what reasons this could have?

Thanks in advance!
Thomas

I changed the Turbulence Model from k-eps to SST but I still get the same error...

The real error is the invalid number floating point exception. There is an FAQ on a similar error: http://www.cfd-online.com/Wiki/Ansys...do_about_it.3F

The issues discussed in the FAQ are likely to apply here.
