Hi,
I have observed that the config_template.cfg offers various options for specifying Hybrid RANS/LES models, including SA_DES, SA_DDES, SA_ZDES, and SA_EDDES. Therefore, does DDES refer to Vorticity Adapted SGS-based DDES or standard DDES, while EDDES refers to Shear-layer adapted SGS-based EDDES? Additionally, is it possible to utilize IDDES in SU2 and if so, how can one obtain it?
Thanks for any help.

These are the models that we have currently, all SGS based:

SA_DES = 1, /*!< \brief Kind of Hybrid RANS/LES (SA - Detached Eddy Simulation (DES)). */
SA_DDES = 2, /*!< \brief Kind of Hybrid RANS/LES (SA - Delayed DES (DDES) with Delta_max SGS ). */
SA_ZDES = 3, /*!< \brief Kind of Hybrid RANS/LES (SA - Delayed DES (DDES) with Vorticity based SGS like Zonal DES). */
SA_EDDES = 4 /*!< \brief Kind of Hybrid RANS/LES (SA - Delayed DES (DDES) with Shear Layer Adapted SGS: Enhanced DDES). */
};

Thanks for your help.
