In the process of complex cloth modelling, the cloth tissues mobile disorderly, resulting in ineffective modeling and other problems. To address the problems mentioned above, a corresponding solution is put forward. Based on the HLA development platform and Vega development platform, a 3D cloth simulation method which improves the simulation algorithm of annealing is proposed. Some related processings are performed on the cloth image, and the moving cloth issues are simulated using the improved fast cloth moving particle model to complete 3D simulation of the cloth. Experimental results show that this method can describe the complex cloth issues accurately, quickly and completely, and achieves desirable results.

In this paper, a new methodology for the design of effective cooling system of thermoplastic injection tools is proposed. It is named MCOOL® for Morpho Cooling. It allows the design of the cooling channels in the mold with no a priori on the number, the size, the shape of the channels and the temperature of the coolant before performing the optimization. Numerical and experimental results obtained on a mold manufactured thanks to this methodology are compared with those coming from a conventional design. The criteria used to discriminate the results are based on the uniformity of the temperature field in the molded part and on the final warpage of the part.
