The real question is whether the CFD solver is differentiable!

Optimizing the bridge only works because my method for solving the forces in each beam (least squares) happens to be differentiable.

There are a bunch of papers on training a neural network to replicate the output of a cfd solver.

Then the network is differentiable.

ooh, using a NN as a solver / simulator would make pretty much anything differentiable :)
