This container recipe is a 'boiler-plate' for those with a license for Ansys Fluent. A user must have licenses and binaries to be able to use Ansys Fluent within the container.
Ansys Fluent is an advanced computational fluid dynamics (CFD) software used for simulating and analyzing fluid flow, heat transfer, and related phenomena in complex systems. It offers a range of powerful features for detailed and accurate modeling of various physical processes, including turbulence, chemical reactions, and multiphase flows.
This installation guide assumes that you have a license for Ansys Fluent and a tar with the Fluent application provided by Ansys.
This example, is using a tar with the name fluent.24.2.lnamd64.tgz.
- ROCm
- Mesa 3D Graphics libraries and XCB Utilities Libraries
- MPI Stack Optional
- OpenMPI/UCC/UCX
- Cray MPI
This example installs Ansys Fluent into /opt, but this is not required.
- Extract tar files
cd /opt
tar -xzvf fluent.24.2.lnamd64.tgz
- Adding Fluent to PATH and setting environment variables
export PATH=/opt/ansys_inc/v242/fluent/bin:/opt/ansys_inc/v242/fluent/bench/bin:$PATH
export ANSGPU_OVERRIDE=1
- Link Fluent Python into Path
ln -s /opt/ansys_inc/v242/commonfiles/CPython/3_10/linx64/Release/python/bin/python /usr/bin/python
or
sudo update-alternatives -set python /opt/ansys_inc/v242/commonfiles/CPython/3_10/linx64/Release/python/bin/python
- Setup external MPI Optional
This example uses local Open MPI installed at/opt/ompi. To use CRAY MPI, point it to the root of the install.
export OPENMPI_ROOT=/opt/ompi
There are 2 License methods for Ansys Fluent. One of the following is required to Run Ansys Fluent on a node.
The ANSYSLMD_LICENSE_FILE environment variable should be set to the AnsysLMD server address that you use.
export ANSYSLMD_LICENSE_FILE=1055@localhost
This example uses a file ansyslmd.ini as the licensing file.
This assumes Fluent is installed in /opt/ansys_inc/
cp ./ansyslmd.ini /opt/ansys_inc/shared_files/licensing/
ANSYSLI_ELASTIC=1
# SSL shenanigans (fixes elastic issue)
capath=/etc/ssl/certs
cacert=/etc/ssl/certs/ca-certificates.crt
echo "capath=/etc/ssl/certs" >> $HOME/.curlrc
echo "cacert=/etc/ssl/certs/ca-certificates.crt" >> $HOME/.curlrc
cd /etc/ssl/certs && wget http://curl.haxx.se/ca/cacert.pem && ln -s cacert.pem ca-bundle.crt
