Introduction to Fluid Dynamics Simulation - CFD Theory and Applications with ANSYS CFX

  • Presential
  • Computational Fluid Dynamics
This course provides participants with the basics of Computational Fluid Dynamics (CFD) giving them the necessary foundation to properly use the ANSYS CFX software. The course intends that future CFD software users will be able to understand the fundamental concepts underlying the numerical methods and approaches used, allowing them to understand the complete generation and solution cycle of a CFD simulation.

Basic aspects of modeling, development of boundary conditions and initials, convergence techniques, selection and special care with meshes and time step and the conceptual notion of EbFVM - Element-based finite volume method are addressed. The latter is a very versatile method, suitable for working with unstructured meshes and used by ANSYS CFX software. Conceptually, we discuss conceptually from the simplified deduction of conservation equations, their integration, application of contour conditions, segregated and coupled solutions, coordinates and structured and unstructured meshes.

The course is structured in three modules: Preparation of geometries with ANSYS SpaceClaim, Generation of Meshes with ANSYS Meshing and Fluid Dynamics Simulation using ANSYS CFX. In this last module, an exclusive period is dedicated to the presentation of CFD concepts. For this complete package, we include as a benefit a reduction of 15% in the value of the investment if compared to the acquisition of the individual modules.
