The 9th International Conference on Physical and Numerical Simulation of Materials Processing (ICPNS’2019 for short) was held in Rusia.

Physical and numerical simulation make it possible to move from the concept of trial and error to scientifically grounded approaches, to build quantitative models and give qualitative understanding of the studied problems. Both of these approaches are dynamically developing and gaining ever growing application in industry and manufacturing technologies of the twenty first century.
