Annotation

Introduction to the OpenFOAM open source package for CFD simulations on HPC infrastructure. The course will guide participants through basic geometry and mesh generation, physical modelling, visualization and parallel computation.

Purpose of the course (benefits for the attendees)

The course provides a tour around all fundamental parts of OpenFOAM. It is useful for new users and beginners in CFD simulations by using open source code.

About the tutor

Tomáš Brzobohatý is a researcher at the Czech IT4Innovations National Supercomputing Center. He is part of a team providing services for industrial partners in the field of CFD and CSM analysis.

Tips and tricks

Prerequisities

Exercises will be run on participants' own laptops - we will provide an OpenFOAM/Linux virtual machine on a USB memory stick, to be run in VirtualBox (PC requirements: >= 30 GB free disc space, >= 4GB RAM).
There are no prerequisites for course participants. Basic knowledge of Linux usage is beneficial.

Registration

Obligatory registration via the PRACE Events Portal (coming soon).

Capacity and Fees

20 participants. The event is provided free of charge.

Practicalities

  • See the links below for how to get to the campus of  VŠB - Technical University Ostrava, and to the IT4Innovations building.
  • Documentation for IT4Innovations' computer systems is available at https://docs.it4i.cz/.

Remark

This training is a PRACE Training Centre (PTC) course, co-funded by Partnership of Advanced Computing in Europe (PRACE). The main web page of the course is located on the PRACE Events Portal.
