Abstract: On the basis of previous explicit
algorithm in mould filling simulation, a new explicit algorithm with fully vectorial
operations is proposed, where the global solution for pressure field is eliminated. It
remains only the matrix operations at element level, by a strategy of feedback correction,
the incompressibility condition is maintained in the filled portion at each time step. As
the algorithm is totally uncoupled, the computational cost is about linearly proportional
to the degree of freedom number. Furthermore, this vectorial uncoupled algorithm can be
easily parallelized for high performance computation with the new appearing
multi-clusters, a first version of the software is developed simultaneously. The
simulation results are compared with commercial software MOLDFLOW to show a proper
performance.
