Introduction to Computational Fluid Dynamics

FSI-MMPAcad. year: 2024/2025

Subject introduces students with capabilities of computational simulations of fluid flow and presents philosophy of work in CFD environment. Emphasis is put on preprocessing, i.e. 3D geometrical modeling and computational grid creation process. Students are also taught the formulation of the computational case and basics of postprocessing. This subject will be followed on by course Computational fluid dynamics . Practical exercises are focused on work with 3D modelers and ANSYS CFD.
