• Code: CConfig.cpp line 2534

GUST_DIR

Direction of the gust X or Y dir

More in config_template.cfg: Direction of the gust (X_DIR, Y_DIR or Z_DIR)

TURB_FIXED_VALUES_DOMAIN

Shift of the fixed values half-space, in length units in the direction of far-field velocity.

More in config_template.cfg: Shift of the half-space on which fixed values are applied. It consists of those coordinates whose dot product with the normalized far-field velocity is less than this parameter.
