Multipoint optimization

amcloughlin801 · November 12, 2014, 17:55

Hi, I'm a new SU2 user.

I was just wondering has anyone ever attempted to perform a multipoint optimization (e.g over a range of mach numbers) by modifying the shape optimization Python script so that it calls the modules multiple times?

Hi Amcloughlin
How to edit the shape_optimization.py in order to perform a multipoint optimization with a range of Mach number or a range of AoA?
Thank in advance.

Hi. Sorry, this is the problem I have as well - I don't know.

The Python scripts create the config_CFD.cfg which is a bare bones version of the config file. My guess is that the values of the variables would need to be changed before this gets created. It could be done in interface.py - something like konfig['Mach number']=0.82 etc, but this would need to be done multiple times for each condition. I would guess that quite a lot of code would need to be modified in the end.

If anyone knows of a procedure for multipoint optimization within the Python scripts, any help would be much appreciated!
