Random Gust input in SU2

[gsivanii]

Hi everyone,

I am working on simulating an unsteady transonic gust response over a 2D airfoil in SU2.

I need to excite the flow domain using a custom, irregular gust velocity timeline instead of a standard smooth wave.

The built-in options in SU2 follow the field velocity approach , but they are restricted to basic mathematical profiles like SINE, ONE_MINUS_COSINE....

Is there an existing feature or configuration setting in SU2 to prescribe a custom, time-dependent gust velocity directly from an external data text file, or must I modify the source code? Crucially, I want this custom input to follow the same background field velocity approach used by the other inbuilt profiles.

Thanks in advance!!

at the moment there is no custom user defined gust besides what the config options provide. You can have a look in the code at :
void CFluidIteration::SetWind_GustField(CConfig* config, CGeometry** geometry, CSolver*** solver)

You can also use the python wrapper to apply custom time-dependent boundary conditions, see for instance the example in TestCases/py_wrapper/custom_inlet

Using the python wrapper for this is the most generic approach I think.
