Title:
TIME PARALLEL PERTURBATION DOMAIN UPDATING METHOD FOR AIRCRAFT DYNAMIC CHARACTERISTIC SIMULATION
Document Type and Number:
WIPO Patent Application WO/2023/168772
Kind Code:
A1
Abstract:
A time parallel perturbation domain updating method for aircraft dynamic characteristic simulation. The method comprises: reading data; obtaining Chebyshev transformation matrix components; initializing a flow field; establishing a dynamic computational domain; solving flow control equations of all time layers in parallel in the dynamic computational domain; updating the dynamic computational domain; determining whether parallel solving in a current time period converges and whether computation is completed, if said solving converges, skipping to solving all the time layers in parallel in the dynamic computational domain, and entering the next iteration step of the parallel solving in the current time period; if the solving at a current moment converges and the computation is not completed, skipping to flow field initialization, and entering the solving in a next time period; and otherwise, outputting a result.
