Ansys fluent for linux

Enable the Use Remote Cluster Head Node field and specify the remote node to which ANSYS FLUENT will connect for spawning (e.g., via rsh or ssh ). If this is not provided, then ANSYS FLUENT will try to use the first machine in the machine file. If SGE is chosen as the job scheduler, then the SGE qmaster will serve the same purpose.

In addition to using the settings in the Remote tab in FLUENT Launcher , the following command line options are also available when starting ANSYS FLUENT from the command line:

-nodepath= is the path on the remote machine where ANSYS FLUENT is installed.

-node0= is the machine from which to launch other nodes.

-nodehomedir= is the directory that becomes the current working directory for all the nodes. Additionally, this will be used as a scratch area for temporary files that are created on the nodes.

-rsh= is the command that will be used to launch executables remotely. This option defaults to rsh.exe but can point to any equivalent program. The form of this command should be that it should not wait for additional inputs such as passwords. For example, if you install SSH, and try to launch in mixed mode using ssh , the launch may fail unless you have set up a login for SSH without a password. For more information about setting up SSH without a password, see http://www.debian-administration.org/articles/152

As there are known issues with launching ANSYS FLUENT in mixed Windows/Linux mode from cygwin, it is recommended that you use the command prompt ( cmd.exe ).

While ANSYS FLUENT case and data files are read from and written to the Windows machine while running mixed Windows/Linux simulations, parallel data files ( .pdat files) are written by the nodes and will not be available on the Windows machine. Therefore, the path specified for writing .pdat files should be a Linux path (you can set node’s home directory if you want to provide relative paths). If you use the graphical user interface to read and/or write .pdat files, the directory component of the path is ignored and only the file name is used to read and/or write the .pdat file relative to the node’s current working directory.

When working with mixed Linux and Windows runs that employ user-defined functions (UDFs), you should keep in mind that the file that you have opened for reading/writing on the host machine will not be available on remote nodes and vice-versa. You may therefore have to transfer data present on the nodes to the host and write it from host, (or distribute the data from the host to the nodes after reading the data from the host).

Setting Job Scheduler Options When Running on Remote Linux Machines

By selecting the Use Remote Linux Nodes option and the Use Job Scheduler option in FLUENT Launcher , you can set job scheduler options for the remote Linux machines you are accessing for your CFD analysis.

When these options are enabled in FLUENT Launcher , you can use the Scheduler tab to set parameters for either LSF , SGE , or PBS Pro job schedulers. You can learn more about each of the schedulers by referring to the Load Management Documentation. The following list describes the various controls that are available in the Scheduler tab:

Use LSF allows you to use the LSF job scheduler.

LSF queue allows you to specify a job queue and enter the queue name in the text box.

Use Checkpointing allows you to use checkpointing with LSF. By default, the checkpointing directory will be the current working directory; however, you have the option of enabling Checkpointing Directory .

Checkpointing Directory allows you to specify a checkpointing directory which is different from the current working directory.

Automatic Checkpoint with Setting of Period allows you to specify that the checkpointing is done automatically at a set time interval. Enter the period (in minutes) in the text box, otherwise checkpointing will not occur unless you call the bchkpnt command.

Use SGE allows you to use the SGE job scheduler.

SGE qmaster is the machine in the SGE job submission host list. SGE will allow the SGE qmaster node to summon jobs. By default, localhost is specified for SGE qmaster . Note that the button allows you to check the job status.

SGE queue is the queue where you want to submit your ANSYS FLUENT jobs. Note that you can use the button to contact the SGE qmaster for a list of queues. Leave this field blank if you want to use the default queue.

SGE pe is the parallel environment where you want to submit your ANSYS FLUENT jobs. The parallel environment must be defined by an administrator. For more information about creating a parallel environment, please refer to the SGE documentation. Leave this field blank if you want to use the default parallel environment.

Use PBS Pro allows you to use the PBS Pro job scheduler.

ANSYS Fluent is a computer-aided engineering software in Computational Fluid Dynamics (CFD) for modeling fluid flow and heat transfer in complex geometries. Fluent allows for complete network change and flow analysis with unstructured networks for complex geometries. The types of meshes that can be generated and received by this software group include grids with triangular and quadrilateral elements (for 2D geometries) and quadrilateral, hexagonal, hierarchical or wedge (for 3D geometries).
Ensys Fluent also allows the user to improve the grid (for example, shrinking or enlarging the grid to the required boundaries and locations in the geometry). This solution for optimization and networking gives the user the ability to refine results in areas with large vortices (such as the boundary layer, etc.). These capabilities significantly reduce the time it takes to produce a good network compared to solving in built-in networks. This software is written in C programming language and uses all the power and flexibility of this language. Fluent enables the use of dynamic memory, a well-structured data and information structure, and flexible computational control.

Features and characteristics of ANSYS Fluent software:

– Proper structure of data and information

– Flexible control of calculations

– Modeling fluid flow and heat transfer

– Having a useful and practical user environment

– Compatibility with Microsoft operating systems

– Having all kinds of meshes and elements, including quadrilateral, quadrilateral, hexagonal, pyramidal or wedge

Ansys 18.2 on UBuntu 16.04: Installation Guide

18Likes

Hi everybody,
since I had a lot of issues installing Ansys on Ubuntu, I summarize here all the steps (some picked up inside this forum) that are required to have a running version. I suggest to use standard MESA driver instead of nvidia or AMD drivers because I also need to use xrdp 0.9.4 (to have remote access) and it does not work with those drivers.

The required packages from the installation guide (for RedHat/CentOS) are:
� libXp.x86_64
� xorg-x11-fonts-cyrillic.noarch
� xterm.x86_64
� openmotif.x86_64
� compat-libstdc++-33.x86_64
� libstdc++.x86_64
� libstdc++.i686
� gcc-c++.x86_64
� compat-libstdc++-33.i686
� libstdc++-devel.x86_64
� libstdc++-devel.i686
� compat-gcc-34.x86_64
� gtk2.i686
� libXxf86vm.i686
� libSM.i686
� libXt.i686
� xorg-x11-fonts-ISO8859-1-75dpi.noarch
� glibc-2.12-1.166.el6_7.1 (or greater)

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

sudo dpkg-reconfigure dash

Then answer «No» to the question.

6. From DVD1 install Ansys, launch:

7. Since you have installled ANSYS as root, you need to change ownership of the ANSYS configuration directories and files so that you have write access to them (if «user» is your username):

sudo chown -R user:user ~/.ansys sudo chown -R user:user ~/.config sudo chown -R 777 /ansys_inc/v182/aisol/WBMWRegistry/

8. Debian-based multiarch distributions have their libc in /lib/x86_64-linux-gnu/ instead in /lib/. So that regular-expression for fetching the libc_version misses because of the two hyphens in x86_64-gnu-linux. After this modification everything seems to be fine.
Locate cfx5arch (probably /usr/ansys_inc/v182/CFX/bin/cfx5arch). In this file you will find near line 196:

if test -n "$libc_file"; then case `basename $libc_file | sed 's/\.so//g'` in glibc-*|libc-[0123].*) # this is almost certainly a glibc version

libc_file_tmp=`echo $libc_file | sed -e 's/x86_64-linux-gnu//g'` and modified the following line from: libc_version=`echo $libc_file | sed -e 's/^[^-]*-//' -e 's/\.so//g'`

libc_version=`echo $libc_file_tmp | sed -e 's/^[^-]*-//' -e 's/\.so//g'`
