Course detail

Materials Modelling I

FSI-WMO-AAcad. year: 2026/2027

Computer modeling of materials is modern tool for study of microstructure and properties of materials and their mutual relationships. Firs part of the course will be dedicated to so called first-principle or ab initio calculations, which are based on basic postulates of quantum mechanics and do not need any experimental input data. Main attention will be focused on different approaches in these methods, their practical applications and also their limits.
In second part of the course attention will be focused on description of semi-empirical method for modeling of thermodynamic functions, calculations of phase diagrams of complex systems and work with them in scientific and engineering applications. Main attention will be dedicated to the CALPHAD method, which is in present times ready for use in industry applications for development of new materials.

Entry knowledge

Good knowledge of graduate courses in mathematics, physics and chemistry, as well as the following subjects of the specialization: Fundamentals of chemical thermodynamics and kinetics, Materials physics,

Rules for evaluation and completion of the course

The course-unit credit is awarded on condition of meeting the following requirements: participation in all exercises, elaborating protocols according the teacher’s instructions.
Examination: Examination is oral. The student explains the theoretical item and describes the way of solving the examples, including basics used of methods and relationships.
The exercises are compulsory and the absence from these exercises must be properly excused. In case of absence the student is required to elaborate a protocol in order to prove that he/she understands the topic.

Aims

Familiarize students with basics of ab initio computational techniques of electronic structure and their applications in material modeling. In addition, students will be familiar with the currently used methods of calculations of equilibrium diagrams, including any relevant software and available database of the relevant thermodynamic data.
Students receive general knowledge about ab inito methods and methods for thermodynamic modeling, which have using for material engineering. They should be able to judge outputs of these methods and also they should be able to carry out own simple simulations.
