Towards an accurate simulation of the crystallisation process in injection moulded plastic components by hybrid parallelisation
International Journal of High Performance Computing Applications(2014)
摘要
The simulation of the crystallisation process during the injection moulding process of plastic components is time consuming, resulting in the ability to simulate only small parts of a component. To remove this constraint and enable the simulation of complex parts, the computing power of high-performance computers is demanded. A further design objective is high scalability in performance and memory consumption on today's and future high-performance computing architectures to allow precise predictions of global part properties. In this work, we present a simulation tool for the crystallisation process and the parallelisation of the tool by a hybrid MPI-Pthreads approach that meets this design objective. We verify the performance and memory consumption of our parallelisation using a large simulation area of a realistic plastic component as a case study and can further predict that entire parts will also be calculable.
