Optimization of mould filling simulation time without losing the efficiency remains an important issue in Resin Transfer Moulding (RTM) process. This study is interested on the improvement of RTM simulation tools in term of efficiency, execution time and space occupation.
The results show that our methodology firstly based on the modification of the conventional control volume/finite element method CV/FEM and secondly on the adaptation of conjugate gradient algorithm to compressed sparse row storage, leads to maximum reduction in calculation time and space memory.
The present approach is validated with respect to available numerical results of classical direct and iterative solvers and with analytical results. Good agreement was found.
The innovation of the present work lies on developing this methodology applicable to the three-dimensional RTM simulation and other engineering fields to describe accurately and with a reasonable computational cost complex physical processes of fluid dynamic occurring in industry.
