Software & Version

RSM 2024R2

*This example was taken from this version but is not necessarily limited to this version.

Description/Cause

Error occurs if the client cannot communicate to this IP address, and the remote computer has multiple NICs (multiple IP addresses). This is the IP address which the Remote Computer’s RSM Launcher service is bound to.  (i.e. This IP address may be a private LAN internal to the remote host/cluster and not accessible to the client.)
 

*The cause(s)/solution(s) we identified in this documented instance may not be the only cause(s)/solution(s) for this error.

Solution

1. On the remote computer (running the RSM Launcher Service) stop the “ANSYS RSM Launcher Service Release XXX” service. (xxx being the current version installed)
2. Open a Command Prompt with Run As Administrator rights and change to the [RSMInstall]\bin directory
   1. (Ex. cd /D "C:Program Files\Ansys Inc.\vXXX\RSM\bin)
3. Enter the following command using the actual IP address of the remote computer as seen by the client computer: rsm.exe appsettings set Global RemotingMachineNameAttribute <IP address>
4. If using RSM internal file transfer mechanism, enter the following command: rsm.exe appsettings set UserProxy SocketTransfererListenerIpAddress <IP address>
5. Restart the “ANSYS RSM Launcher Service Release XXX” service.
