Abstract:

The pre-processing module is a core component of casting numerical simulation software, directly influencing the accuracy and efficiency of simulations. This paper presented a comprehensive review of pre-processing techniques in casting simulation, with a specific focus on geometric modeling, parameter configuration, and the pivotal mesh generation techniques. The principles and evolutionary history of hexahedral, tetrahedral, and hybrid meshing methods were elaborated. Furthermore, the strengths and limitations of various algorithms in handling complex castings were analyzed. Finally, the paper identified key challenges currently facing pre-processing modules and outlined future development trends.
