Part of:


One of the new trends in today’s numerical simulation of material processes is to combine physical and data-driven techniques to create an efficient and cross-scale virtual framework. An effective use of appropriate material models and agile numerical tools capable of dealing with sophisticated nature of material evolution during processes have broadly been attempted to provide answers to the best ways of processes optimizations. With the introduction of Integrated Computational Material Engineering (ICME) frameworks for material process handling & linking, the need for hybrid modelling approaches with sound physical\mathematical basis and affordable computational time, has undoubtedly raised. New cross-scale hybrid methods with multi-solver capability, agility, flexibility and user-friendly interfaces have recently been introduced. Attempts are also made to setup full computational frameworks for the Through Process Simulation (TPS) of materials within manufacturing production chains. In this research paper, some analytical and computational aspects of casting process have been investigated using hybrid physical and data-driven approaches. The cooling and solidification phenomena during casting process are addressed and fresh ideas on hybrid physical-data driven modelling (using Genetically Algorithm Symbolic Regression, GASR) and their process applications are tersely presented.

Handling of simultaneous and/or sequential modelling at various phases, physics, scales and times during TPS of complex material processes is one of the difficult challenges of modern simulation frameworks. In the research work herein, the effects of increasing computational power, parallelization and efficient interfacing technologies on hybrid material modelling and its implications for future of material modelings are shortly reviewed. In addition, some technical aspects of new evolving domain and dynamic mesh technique for continuous and semi-continuous casting are also presented and their integration with the hybrid modelling framework for material and process simulations are concisely discussed. In the final part of the paper, the contagious concepts of interfacing and multi-domain solutions schemes are briefly scrutinized and their application to multi-phase casting process simulations are highlighted using combined analytical and process-based GASR technique for a simple case study.
