SU2 shape optimization initialization method?

gina07 · April 10, 2015, 05:49

Dear friends in SU2，
I am concerned about the initialization of fluid field in every iteration.Does Su2 use the same 0 as the initialization quantity to initialize the physical field in every iteration after the mesh change? I think it is quite a time-consuming method. Can SU2 use the convergent solution of previous step to initialize the field and use the dynamic grid as well?
Waiting for someone to help me.

Yours,
Gina

Yes, SU2 uses the nearest design's results as the initial starting state for the next flow evaluation. The state's attribute 'state.pullnlink' gets the file names of nearest design's results, and the 'redirect' function is used to link the results files to the new design folders. Hope this will help you. A further look into the code, or carry out step by step operation according to the python code manually, then you will find that.
