چکیده

A method is presented for controlling element sizes on the interior of areas during surface meshing. A Delaunay background mesh is defined over which a neighborhood based interpolation scheme is used to interpolate element sizes. A brief description of natural neighbor interpolation is included and compared to linear interpolation. Two specific applications are presented that utilize the sizing function, namely boundary layer meshing and surface curvature refinement. For these applications, criteria used for insertion of additional interior vertices into the background mesh to control element sizing is discussed.

Simulation and Experimental Study of Vibration and Noise of Pure Electric Bus Transmission based on Finite Element and Boundary Element Methods

Since the electric motor of pure electric vehicle replaced the engine, the "masking effect" disappears, and the problem of vibration and noise of the transmission becomes prominent. This is generated during the gear meshing and is transmitted to the housing through the shaft and bearing. Thereby, radiation noise of the housing are generated. The prediction and analysis...

Automatic Boundary Sizing for 2d and 3d Meshes

1 ABSTRACT The numerical solution of problems in science and engineering via the finite element method requires, as a first step, the discretization of a domain into a set of simply shaped elements. Determining the size of these elements along the domain, including the boundary, to form well-shaped elements is a difficult task. We present in this paper a simple technique, called smart sizing, w...
