writing geometry results in unsteady adjoint solver

[KwongiLee]

Dear Professor He Ping,

When using unsteady adjoint solver, i want to save results(shape, hydrodynamic variables, etc.) every time step by all design iteration.
However, when i run the cylinder tutorial(unsteady tutorial), only the results of final design are saved in time folder ( 0.01s ~ 3.00s). Is it right?
If i want to modify these saving setting, how can i do and what file related?

Yeah, unfortunately, we do not support this feature. DAFoam will overwrite solutions from previous iterations. Saving all intermediate optimization steps for unsteady cases requires a lot of space, and we are trying to avoid that.. A workaround is to add some lines here:

dafoam/dafoam/mphys/mphys_dafoam.py

Line 1317 in 9c996da

def compute(self, inputs, outputs):

to copy the intermediate steps to somewhere else
