“…Alternatively, an initial microstructure description can be developed with numerical methods (e.g., with Cellular Automata). 3 The latter approach is more flexible; however, a reliable projection of material history into a computationally generated description is a demanding task.…”

We present a process of semantic meta-model development for data management in an adaptable multiscale modeling framework. The main problems in ontology design are discussed, and a solution achieved as a result of the research is presented. The main concepts concerning the application and data management background for multiscale modeling were derived from the AM3 approach-object-oriented Agile multiscale modeling methodology. The ontological description of multiscale models enables validation of semantic correctness of data interchange between submodels. We also present a possibility of using the ontological model as a supervisor in conjunction with a multiscale model controller and a knowledge base system. Multiscale modeling formal ontology (MMFO), designed for describing multiscale models' data and structures, is presented. A need for applying meta-ontology in the MMFO development process is discussed. Examples of MMFO application in describing thermo-mechanical treatment of metal alloys are discussed. Present and future applications of MMFO are described.

“…Cellular automata (CA) models [15] occupy the first place among the methods used in the computer modeling of microstructure evolution. CA are used for modeling of crystallization (solidification) [16][17][18][19][20], dynamic and static recrystallization [21][22][23][24][25], phase transformation [23,[26][27][28][29], grain refinement [30][31][32][33], etc.…”

“…During casting, the refractory lining of the tundish and the slag powders used guarantee the thermal stabilization needed for maintaining the casting temperature required for a given steel grade. Because of the liquid steel residing in the tundish for a specific duration (which is limited by the tundish capacity and the casting speed), it is essential to monitor the tundish operation by analyzing the hydrodynamic conditions [3][4][5]. The main and side liquid steel stream present in the tundish working space form a complex metal circulation pattern.…”

This paper presents the results of computer simulations and laboratory experiments carried out to describe the motion of steel flow in the tundish. The facility under investigation is a single-nozzle tundish designed for casting concast slabs. For the validation of the numerical model and verification of the hydrodynamic conditions occurring in the examined tundish furniture variants, obtained from the computer simulations, a physical model of the tundish was employed. State-of-the-art vector flow field analysis measuring systems developed by Lavision were used in the laboratory tests. Computer simulations of liquid steel flow were performed using the commercial program Ansys-Fluent R . In order to obtain a complete hydrodynamic picture in the tundish furniture variants tested, the computer simulations were performed for both isothermal and non-isothermal conditions.Keywords: tundish, steel flow, numerical simulation, PIV method W pracy przedstawiono wyniki symulacji numerycznej i eksperymentów laboratoryjnych opisujących ruch stali w kadzi pośredniej. Analizowanym obiektem była jedno-wylewowa kadź pośrednia przeznaczona do odlewania wlewków płaskich. Do walidacji modelu numerycznego i weryfikacji warunków hydrodynamicznych występujących w analizowanych wariantach zabudowy kadzi pośredniej zastosowano symulacje komputerowe i fizyczny model kadzi pośredniej. W eksperymentach laboratoryjnych do analizy wektorowego pola przepływu zastosowano system pomiarowy firmy Lavision. Symulacje komputerowe przepływu ciekłej stali wykonano programem Ansys-Fluent R . W celu zyskania pełnego obrazu hydrodynamiki ruchu stali w analizowanym obiekcie symulacje komputerowe wykonano dla warunków izotermicznych i nieizotermicznych.
