| Abstract: | A novel method which used the parallel algorithm to simulate the process of mold-filling in RTM was proposed.Based on this method we programmed a parallel numerical software to simulate the process of moldfilling in RTM for a 2D shape thin parts and predict the resin flow front advancement and the distribution of pressure field at any instant in time.And good agreement is found between the results and other investigations.Numerical examples show that parallel numerical algorithm can reduce the calculation time and improve the calculation efficiency. |
