Computational Fluid Dynamics
Industry case study
Several industrial cases will be presented, executed by SimTec or its customers with the aid of ANSYS Fluent general-purpose 3D CFD package. The examples are taken from industrial applications in SE Europe countries but emphasis will be given on the Slovenian cases. The applications cover the industry sectors of marine, constructions (HVAC), chemical, pharmaceutical, hydraulic, metal, power...

An industrial CFD case will be executed as a workshop. The setup, solution and postprocessing will span through the first half of the session. The second half will be spent with experimentation of alternative solutions (e.g. changing BCs, material properties, mesh size, etc.) and discussion regarding best practices, error reduction and accuracy, tips and tricks, parallel computing efficiency, etc.

The aim will be to test some of the requirements presented in the course (such as mesh-partitioning and load balancing) to achieve high-scalability on massively parallel computers (maybe also on GPUs).
Two examples are used to illustrate these concepts: a multi-block structured code (elsA) and an unstructured code (AVBP). Parallel computing strategies used with both flow solvers are...
