Hello Everyone,

I've just started compiling journal files for a fully converged RANS case for RSM and needed to implement second order discretization schemes for the solution. However, whenever I run my cases on the HPC Cluster, I've noticed that my Turbulent Kinetic Energy (TKE) remains in First Order Upwind and despite setting the 'k' discretization to 1 (Second Order). Am I missing something here? Here's a sample of how I am activating the case using RSM:

/mesh/check-before-solve? y
/solve/initialize/repair-wall-distance y
/define/models/viscous reynolds-stress-model yes
/solve/set/discretization-scheme/drsm 1
/solve/set/discretization-scheme/k 1
/solve/set/discretization-scheme/pressure 13
/solve/set/discretization-scheme/epsilon 1
/solve/set/discretization-scheme/mom 1
/solve/set/under-relaxation/body-force 1
/solve/set/under-relaxation/epsilon 0.7
/solve/set/under-relaxation/pressure 0.3
/solve/set/under-relaxation/density 1
/solve/set/under-relaxation/k 0.8
/solve/set/under-relaxation/turb-viscosity 0.8
/solve/set/under-relaxation/drsm 0.3
/solve/set/under-relaxation/mom 0.5
/solve/iterate 2000


Can anyone assist me in this regard?

Thank you,
SNS.
