ANSYS

Current versions of ANSYS are installed to directories under the path

/home/SOFT/ansys_inc/

Note, that connection have to be opened with the X11 forwarding if you want to launch the graphical interface (Linux: ssh -Y; Windows: active X server and Enable X11 forwarding in PuTTy).

Submitting the job to Slurm scheduler is described under this link.

Beside their standard location, Ansys-workbench and Ansys-Fluent may be called by their own commands, see the table below.

The commands to start each environment are listed in the table above.

ANSYS offers two environments to work in:

• MAPDL – the original working environment, started with the command

launchxxx

• Workbench – new environment, launched with the command

wbxxx

Fluent is launched with the command

fluentxxx

Working in interactive mode directly on the servers is not very comfortable. Servers are primarily for computing and have little graphics power. It is preferable to prepare the task interactively on the PC and then run the calculation on the servers. The results can then be viewed again on the PC.

Documentation for batch mode is located in the program help in

ANSYS Documentation -> Mechanical APDL -> Operation Guide -> 3. Running the Mechanical APDL Program -> 3.4 Batch Mode

The calculation is started with the command

ansysxxx -b -p productvar < inputname > outputname 2>&1

If we want to run the calculation in the background, then with the command

nohup ansysxxx -b -n nnn -p productvar < inputname > outputname 2>&1 & 

where xxx corresponds to the version (172, 190, 193, 201), nnn is the number of cores used (max 16) and productvar specifies the license used. The values are given in the following table. If the license is not directly specified, Academic Teaching is used.

If the ansysxxx command doesn't work (no link is created in /usr/local/bin), you need to write out the full path

/ansys_inc/vxxx/ansys/bin/ansysxxx -b -p productvar < inputname > outputname 2>&1
