-Mesh data (FEM)-
About mesh data:
As for this mesh data, geometries of diffusers on a wall are simplified (ref. Fig. (c)). First, the domain is divided into 23 areas shown in Fig. (a) and (b), i.e. one regular area and 22 irregular areas. Next, each area is divided into some elements.
Note:Finite elements: The use of hexahedron 27-node isoparametric acoustic spline elements is assumed.
Max length of element: 0.1245 m
Number of elements: 1102080
Number of nodes: 8926001
