Patent number: 11042674Abstract: The description describes one or more processing devices and one or more hardware storage devices storing instructions that are operable, when executed by the one or more processing devices, to cause the one or more processing devices to perform operations including modeling the porous material as a two-dimensional interface, in a simulation space, in which fluid flows and sound waves travel through the porous material and experience pressure and acoustic losses. The operations also include simulating, in the simulation space, fluid flow and propagation of sound waves, the activity of the fluid being simulated so as to simulate movement of elements within the simulation space and across the interface, where the simulation of the movement of the elements across the interface is governed by the model.Type: GrantFiled: October 10, 2017Date of Patent: June 22, 2021Assignee: Dassault Systemes Simulia Corp.Inventors: Adrien Mann, Chenghai Sun, Hudong Chen, Raoyang Zhang, Franck Léon Pérot

Patent number: 10831952Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing data representing the effect of tortuosity on the acoustic behavior of a fluid in a porous medium. One of the methods includes generating by a first data processing program of the data processing apparatus, a model of acoustic behavior of a fluid in a porous medium including an effect of tortuosity, with the model comprising a time variable indicative of a sound speed of the fluid. The method includes rescaling the time variable of the model based on the sound speed in a fluid in the porous medium. The method also includes simulating the acoustic behavior including the effect of tortuosity of the porous medium based on the rescaling of the time-related variables within the model.Type: GrantFiled: March 12, 2019Date of Patent: November 10, 2020Assignee: Dassault Systemes Simulia Corp.Inventors: Chenghai Sun, Franck Léon Pérot, Raoyang Zhang, Hudong Chen, David M.

Patent number: 10386212Abstract: A system and method for simulating activity of a fluid in a volume that represents a physical space, the activity of the fluid in the volume being simulated so as to model movement of elements within the volume. The method includes at a first time, identifying a first set of vortices in a transient and turbulent flow. The method includes at a second time that is subsequent to the first time, identifying a second set of vortices. The method includes tracking changes in the vortices by comparing the first set and the second set of discrete vortices. The method includes identifying one or more noise sources based on the tracking. The method includes determining the contribution of one or more noise sources at a receiver. The method also includes outputting data indicating one or more modifications to one or more geometric features of a device or an entity.Type: GrantFiled: June 22, 2016Date of Patent: August 20, 2019Assignee: Dassault Systemes Simulia Corp.Inventors: Adrien Mann, Franck Léon Pérot
