Abstract
A computer-implemented simulation method for use in a molding process comprises steps of specifying a simulating domain corresponding to a genuine domain in a mold disposed on a molding machine, wherein the genuine domain has a mold cavity to be filled with a fluid having fibers from the molding machine in order to prepare a molding product; performing a virtual molding to generate a shear rate distribution of the fluid having the fibers in the simulating domain while using a molding condition for the molding machine; and calculating an orientation distribution of the fibers by taking into consideration an anisotropic rotary diffusion effect of the fibers and the shear rate distribution, wherein the anisotropic rotary diffusion effect is determined by taking into consideration a square of a rate-of-deformation tensor.
