The focus of this course with its 12 lectures and about 5 practical exercises is targeted on students, PhD's and researchers with good knowledge in the fundamentals of fluid mechanics, numerical methods of fluid mechanics and potentially with some first experience in Computational Fluid Dynamics (CFD). The course will focus on the introduction to the ANSYS Fluid Dynamics software package ANSYS CFX with its components CFX-Pre, CFX Solver Manager and CFD-Post. Further, participants will be familiarized with the main steps of the typical CFD workflow, in particular with CFD preprocessing / CFD setup creation, serial and parallel solver execution and CFD postprocessing in ANSYS CFX. Correctness of boundary conditions and CFD setup specifications, solver convergence control, solver monitoring, customization capabilities of the solvers and the postprocessing as well as recommended CFD best practices are covered.
The course further focusses on the usage of the ANSYS CFX software in a typical Linux cluster environment for massively parallel computations. This includes a basic Linux primer, introduction to LRZ HPC systems and network environment, intro to the use of the SLURM scheduler, CFD remote visualization and aspects of successful CFD simulation strategies in such an HPC environment. Finally some aspects of advanced workflow automation using Python as scripting language in combination with the CCL/CEL scripting language of ANSYS CFX are targeted as well.
All software components introduced in the ANSYS CFD Short Course are available at LRZ via the ANSYS Multiphysics Campus license (for the course participants during the course, and for members of TUM, LMU, HM in general and beyond the course).
Course participants are required to install ANSYS Release 2021.R2 on their own computers, accessing the ANSYS Academic Teaching licenses provided by LRZ in the MWN network. Therefore participants of the course are being provided with an own VPN-enabled user account on the LRZ Linux Cluster CoolMUC-2 (CM2) for the time of the online course. Practical exercises using the ANSYS CFX software tools are then partially carried out on particpants own computers by using local ANSYS 2021.R2 installations and partially by carrying out HPC simulations on the CoolMUC-2/3 clusters using ANSYS licenses being provided by LRZ. Alternatively the ANSYS Free Students Edition 2021.R2 can be used by participants for preparational steps on their own computers at home as well (not requiring VPN access to LRZ license servers).
The ANSYS software is available for Win-10 and Linux operating systems (Open-SuSE, Cent-OS, no Debian based Linux systems).
The course combines lectures and hands-on sessions. Registered participants will be timely informed about the video conference information.
What participants will not learn in this course?
This course is addressed to young scientists, PHD students and under-graduate students (Master level) with so far limited to no experience with Computational Fluid Dynamics (CFD), but with the aim to use in future the High-Performance Computing (HPC) resources of the LRZ for their fluid mechanics oriented research. Basic knowledge of Linux and LRZ computer environment is a plus.
The CFD and HPC exercises will be done partially on participants own PC’s (Win-7/-10 Professional or Open-SUSE/Cent-OS required, no Debian-based Linux supported) and on the Linux Clusters (CM2) at LRZ. Files of the practical exercise sessions are made available to participants.
