Numerical simulation of mold filling in resin transfer molding using isoparametric method
- 102 Downloads
The mold filling of RTM was simulated based on the control volume finite element method (CV/FEM). The formulation using isoparametric transformation was discussed in detail and a computational code based on isoparametric technique was developed. The simulation results were compared with experimental data. Different isoparametric elements, quadrilateral and triangular, were compared in the simulation. It demonstrates that the use of bilinear quadrilateral isoparametric elements in simulating the process can produce a higher precision and cost a less time than the use of triangular ones.
