Use of RNG subgrid scale model with LES model in FLUENT-6.2 and beyond
Is it possible to use RNG subgrid-scale model in FLUENT? I am not able to find any option in GUI to enable RNG subgrid model. This option was available in previous versions.
It is possible to use the RNG subgrid model in FLUENT. From FLUENT Version -6.2 onwards, it is not available in the GUI by default. This is been replaced by WALE model as WALE model shows better performance than RNG subgrid model.
However, when LES model is enabled in main GUI, one can enable use of RNG model by using following command on FLUENT window (including the brackets)
This option makes the choice of RNG model available in GUI and you can choose that from GUI directly.
