Document Type and Number:
Japanese Patent JP2003518672
Kind Code:
A
Abstract:
A computer arrangement and a method for generating meshes of an object having an object volume within a shape defined by a front surface, a rear surface and an envelope surface in accordance with the following steps: (a) receiving input data regarding a set of line sections; (b) defining a circle with a radius Lcirc just large enough to enclose an outer contour of a front surface cross-section; (c) dividing each of the line sections into a number of consecutive line elements connected by nodes in accordance with equation: (1), where: nel(n)=number of line elements of line section 25(n), Lsect(n)=length of line section 25(n), c1, c2=predetermined constants; (d) generating front surface meshes; (e) copying the front surface meshes to the rear surface; (f) generating envelop surface meshes for the envelop surface; (g) generating a volume mesh for the object volume.
