粒子法による鋳造CAEの開発と展開

抄録

In computer aided engineering (CAE) of the casting process, it is necessary to simulate the flow behavior including free boundary and moving boundary, the heat transfer phenomenon, and solidification phenomena adequately. The particle-based methods are numerical analysis method of the Lagrangian algorithm, and there is an expectation that it can analyze casting processes which the numerical solution technique of Eulerian algorithms are not suitable for. Therefore, we report on the research situation of the particle-based method simulator in the casting field centering on the case studies conducted by the authors.
