FSI and Turbulent Flow

I am trying to use the turbulent k-epsilon model in the chemical engineering module with fluid-Structure Interactions (FSI). Since my problem is an FSI case with turbulent fluid flow, I must use turbulent model with the FSI feature. While trying to solve the problem, It gives a message
"Error: 6250
Failed to evaluate variable Jacobian.
- Variable: T_x_chns2
- Geometry: 1
- Boundaries: 16,17,42,47"

Kindly guide me if I am not selecting the modules properly or not coupling it propoerly. Kindly suggest what should I do. The file is attached for reference.
Thank you

Re: FSI and Turbulent Flow

Hi,

did you suceed in implementing FSI and Turbulent Flow? I am facing the same problem...
For the simple Navier-Stokes application mode (ns), the application variable for Total Force per Area is T_xi. In chns, there is only T available, described as Total Force per Unit Area. I therefore tried T_chns, for all 3 directions (x,y,z), but I still get the same error message.

Failed to evaluate variable
- Variable: T_chns

Any suggestion? Thanks.
