MESH CREATION APPARATUS AND MESH CREATION METHOD

WIPO Patent Application WO/2022/249694

A1

A mesh subdivision unit (22) of a mesh creation apparatus (1) subdivides a computational mesh of a flow field until a physical amount evaluated by a physical amount evaluation unit (23) converges, forms a noise source region (421) that includes a main noise source (401) and an auxiliary noise source (402) by defining the physical amount present after convergence as the auxiliary noise source (402), forms a sound evaluation region that includes the noise source region (421) and a propagation route region (422) by defining a sound propagation route from the noise source region (421) to an evaluation point (403) as the propagation route region (422), and subdivides a computational mesh of the sound evaluation region until a sound in the sound evaluation region evaluated by a sound evaluation unit (24) converges.
