This internal Wiki is meant to keep up to date information on the procedure of setting up and maintain both the ANSYS and STAR CCM + software licenses. 

====== ANSYS ======

The ANSYS license server is accessed via **login1** and port **1055** or **chpclic1** and port **1056**. It is always preferred to use **login 1**.

The license files are located under the following dircetory on **login1**:

<code bash>
/apps/chpc/compmech/CFD/ansys_inc/shared_files/licensing/
</code>

and on **chpclic1**:

<code bash>
/apps/chpc/compmech/CFD/ansys_chpclic1/shared_files/licensing/
</code>

The license file will have an *.lic extenstion.

<code bash>
ansysLnd.lic
</code>

Confirm that the M.A.C adress on the license file matches the one of the cluster by using the command //iconfig// to find the adddress ending in *.fca0

The interconnect port is set to **port 2325**

Check out [[howto:ansys|https://wiki.chpc.ac.za/howto:ansys]] for more information. 

To check if the license server is up and running, from **login1**, the command //telnet// can be used:

<code bash>
telnet login1 1055
telnet login1 1056
telnet login1 2325
</code>

To start and stop the license the following commands are used:

<code bash>
start_ansysli
stop_ansysli
</code>

A file in the license folder, **ansys.opt**, contains the list of approved users. The license needs to be stopped and restarted if any changes are made to this file.

The **lmcenter** is used to manage the license usage. A web broswer needs to be launched first by loading the Firefox module:

<code bash>
module load chpc/compmech/firefox/
</code>

The **lmcenter** is started and stopped with the following commands:

<code bash>
start lmcenter
stop lmcenter
</code>

====== STAR CCM+ ======

The STAR CCM + license is accessed through **chcpclic1** and ports **1999** and **2099** (vendor daemon).

<code bash>
telnet chpclic1 1999
telnet chpclic1 2099
</code>

The command //ps ux// can be used to check if the process is running. More information can be found on [[howto:starccm|STAR-CCM+]]
