Shape Optimization: Solution restarting procedure & Exporting shape as 3D CAD Model

JyothiKumar · January 9, 2018, 05:21

Dear SU2 Team Members,

Greetings! We are very happy to inform you that we are exploring the aerodynamic shape optimization script of SU2 R 5.0.0 (Raven) with different configurations. And we would also like to seek your assistance in connection with the following two issues:

1. We are not getting any clue on restarting procedure of the optimization process from previously finished cycles.

2. Is there any way for exporting the intermediate / final optimized geometry as 3D CAD model.

Thanking you in advance.

Regards,
Jyothi Kumar Puttam.

to restart an optimization you typically add the -r project.pkl to the shape optimization script. If you want to start from scratch you can use the final grid that has been used in the last DSN iteration (DIRECT folder).
There are new tutorial in the SU2 v6.0 version of the code that could be interesting for you.

From SU2 to CAD is challenging... there are some commercial solutions but one easy method is to use the slicing capability of SU2 to obtain the airfoil sections (SU2_GEO could be useful if you define GEOMETRY EVALUATION PARAMETERS correctly).

Francisco
