From: A hybrid interface preconditioner for monolithic fluid–structure interaction solvers
Iteration counts and timings for hybrid preconditioners applied to mesh pw6 of pressure wave example on 256 parallel processes—iterations, setup and iteration timings are almost constant over all time steps. Application of the hybrid preconditioner leads to a reduction of iterations and solver time for every type of underlying physics-based block preconditioner. The additional setup cost for the hybrid preconditioner is amortized
