The following instructions only apply, if you are a TUM student or employee

Currently available version 19.1, last tested version 19.1 on 11.9.2018.

  1. To start working with the Fluent Adapter you need to get Fluent. It is available from the following LRZ website.
  2. For running Fluent on Linux PC using Centos 7 is recommended, since it has all necessary libraries. However, it also seems to be possible to get all the libraries for Ubuntu (see below).
  3. ANSYS Teaching products need a connection to a license server. Follow the instructions on the LRZ website.

After the installation you have two programs installed: Fluent and ANSYS Workbench. Fluent is the CFD-solver and the workbench can be used for creating geometries, meshing and setting boundary conditions.

If you are using ANSYS 18.2: Fluent is started by running $ ansys_inc/v182/fluent/bin/fluent from a shell. Workbench is started by running $ ansys_inc/v182/Framework/bin/Linux64/runwb2.

If you are using ANSYS 19.1: Fluent is started by running $ ansys_inc/v191/fluent/bin/fluent from a shell. Workbench is started by running $ ansys_inc/v191/Framework/bin/Linux64/runwb2.

Remark: depending on your system settings, the folder ansys_inc might be installed at different location. usr is usually a good place to start looking for ansys_inc.

Consider adding the folders from above into your .bashrc to start fluent and the ANSYS workbench without having to type the full path. Fluent can also be started from the workbench GUI (Choose Fluid-Flow (Fluent), double-click on setup opens fluent).

ANSYS on Ubuntu

tested on 11.9.2018 with ANSYS 19.1 and Ubuntu 16.04. The following instructions originate from https://www.cfd-online.com/Forums/ansys/199190-ansys-18-2-ubuntu-16-04-installation-guide.html.

If you want to install ANSYS on Ubuntu, you have to do the following steps before starting the ANSYS

  1. run sudo apt install xterm lsb csh ssh rpm xfonts-base xfonts-100dpi xfonts-100dpi-transcoded xfonts-75dpi xfonts-75dpi-transcoded xfonts-cyrillic libmotif-common mesa-utils libxm4 libxt6 libxext6 libxi6 libx11-6 libsm6 libice6 libxxf86vm1 libpng12-0 libpng16-16 libtiff5 gcc g++ libstdc++6 libstdc++5 libstdc++-5-dev

  2. manually install libXp. You can download the binaries from https://pkgs.org/download/libxp6. Install the binaries via sudo dpkg -i libxp6_1.0.2-2_amd64.deb.

  3. Update the database with sudo updatedb.

  4. Run sudo dpkg-reconfigure dash.

  5. Install ANSYS via the install assistant. Go to CD1/iso1 and type sudo ./INSTALL.

  6. (optional) change ownership, if you don't want to always run ANSYS as sudo.

sudo chown -R user:user ~/.ansys
sudo chown -R user:user ~/.config

If you use ANSYS 18.2 run

sudo chown -R 777 /ansys_inc/v182/aisol/WBMWRegistry/

or for ANSYS 19.1 run

sudo chown -R 777 /ansys_inc/v191/aisol/WBMWRegistry/
  1. Test your installation by starting the workbench.

Troubleshooting:

  • if ANSYS runs into problems when trying to connect to the license server, make sure that the following ports are open 1055, 1056, 2325. You can check open ports by typing sudo netstat -ntlp
