turbulent fluid simulation errors

Hi,
I´m trying to simulate a cold plate with some heat generation on the top of it. (that is transferred to the cold plate) I´m using the module:
heat transfer module-->fluid thermal interaction-->Turbulent non isothermal flow kw.
My problem is that when I try to run the model I have this error:
Segregated group X3
Failed to evaluate variable.
- Variable: qwf_htgh
- Geometry: 1
- Boundaries: 558,559,560,561,562,563,564,565,566,567, ...
Failed to evaluate variable.
- Variable: q0_htgh2
- Defined as: (-qwf_htgh)
Failed to evaluate expression.
- Expression: d(((dVolbnd_htgh2*q0_htgh2*test(Ts))-(0))*(dvol),{test@0})
If somebody knows why this error shows up, please let me know. Thanks in advance!

Hi Ann, I think it is this problem:
www.comsol.com/support/knowledgebase/1081/
Make sure to update to the latest release/patch of COMSOL.
