The chapter presents an idea of constructing a scientific workshop focused on high‐temperature processes, based upon a concept of integrated modelling combining the advantages of computer and physical simulations. Examples of physical simulation results aiming at determining necessary material data and high‐temperature characteristics for the needs of computer simulations are presented. They are complemented by an outline of numerical 3D models developed and results of test simulations of a 3D solver of the finite element method (FEM) and the smoothed particle hydrodynamics (SPH). This chapter is closed with a short summary, indicating trends in further research focused on a further development of the DEFFEM simulation package and research and measurement methods.

The chapter presents experimental problems related to research aiming at obtaining data necessary to formulate a physical model of deformation of steel containing a zone consisting of a mixture of the solid and the liquid phases. This issue is strictly related to the application of the soft‐reduction process in integrated strip casting and rolling. The original part of the developed methodology is the experiment computer aid performed with the proprietary simulation package DEFFEM. In order to solve problems related to the deformation of materials with a semi‐solid core or at extra‐high temperatures, comprehensive tests were applied, which covered both physical modelling with a Gleeble 3800 thermo‐mechanical simulator and mathematical modelling. Examples of research findings presented in this chapter show that the developed methodology is correct in the context of experiment computer aid and show the need to develop software in order to implement full 3D models.
