Adjoint-based gradient estimation from gray-box solutions of unknown conservation laws
Han Chen, Qiqi Wang
Many engineering applications can be formulated as optimizations constrained by conservation laws. Such optimizations can be efficiently solved by the adjoint method, which compute…
Unsteady adjoint of pressure loss for a fundamental transonic turbine vane
Chaitanya Talnikar, Qiqi Wang, Gregory M. Laskowski
High fidelity simulations, e.g., large eddy simulation are often needed for accurately predicting pressure losses due to wake mixing in turbomachinery applications. An unsteady adj…
The swept rule for breaking the latency barrier in time advancing PDEs
Maitham Makki Alhubail, Qiqi Wang
This article investigates the swept rule of space-time domain decomposition, an idea to break the latency barrier via communicating less often when explicitly solving time-dependen…
Simultaneous Single-Step One-Shot Optimization with Unsteady PDEs
Stefanie Günther, Nicolas R. Gauger, Qiqi Wang
The single-step one-shot method has proven to be very efficient for PDE-constrained optimization where the partial differential equation (PDE) is solved by an iterative fixed point…
