A computer arrangement and a method for generating meshes of an object havin g an object volume within a shape defined by a front surface (59), a rear surface (59') and an envelope surface (65) in accordance with the following steps: (a) receiving input data regarding a set of line sections (25(n)); (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 (25(n)) into a number of consecutive line elements connected by nod es (17) 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 (59'); (f) generating envelop surface meshes for the envelop surface (65); (g) generating a volume mesh fo r the object volume.
