Speedup of simulation for SIL Interface
Hello, when I carried out the simulation in Matlab, I found that the main part of calculation time is due to advanceTurbineSimulation(), and the device used for calculation was just one of CPUs/GPUs. Now I knew how to choose device by calling createInstance(), do I have any method to choose more CPUs and GPUs at the same time to speed up a single simulation? Thank you!
Best Regards,
Chen
Hello Chen,
your observation makes sense, as a call to advanceTurbineSimulation() progresses the simulation and solves the aeroelastic problem.
The device selected during the call to createInstance() is only used during the free vortex wake calculations. If you’re simulating with unsteady polar BEM, changing this device will not impact performance at all.
Other parts of the code have already been optimized with parallelization through OpenMP, wherever applicable. Thus, there are no additional settings available to further increase simulation speed through device selection.
To improve simulation speed, one approach is to reduce the resolution of the model being simulated, such as adjusting wake resolution, timestep size, structural and aerodynamic discretization, or the number of components within the wave field in offshore simulations, the frequency resolution of potential flow databases etc…
Furthermore, QBlade-EE offers a significant speedup for both structural and aerodynamic evaluations.

David
