Remote Analysis Troubleshooting

Issue

Solution

When you try to solve from a local to a remote machine, an engine process starts on the remote machine, but the Designer user interface hangs indefinitely.

This occurs if the remote solve option is enabled after the COM daemon is started, or when the option "Don't allow exceptions" is selected for the Windows firewall.

Remote solve requires either that the firewall exceptions be turned ON, or that the firewall itself be completely turned OFF.

When you try to solve from a local to a remote machine, you receive the following error message:

“[error] Unable to locate or start COM engine on 'nomachine' : Unable to reach AnsoftRSMService. Check if the service is running and if the firewall allows communication. (10:57:13 PM Aug 13, 2009)”

This error message can occur if the machine is not present, if the network connection is down, if there are firewall issues, or if the service is not running.

Remote Solve Node = Windows

Error: "Unable to locate or start COM engine on <remote node>: Unable to reach AnsoftRSMService. Check if the service is running and if the firewall allows communication."

1. Try disabling the firewall.

2. Confirm that you have not changed the Ansoft Service Port from the default setting of 32958 via Tools > Options > General Options > Analysis Options. If the Service Port has been altered, change it back to 32958, then restart Designer and try to solve again.

3. Make sure that the local machine is able to contact the RSM port on the remote node:
a. Open a command prompt on the local machine and type telnet <remote node name> 32958. If the terminal appears to be hanging, then the connection was successful.

4. Check to make sure that the Ansoft Communication Service is running:
a. Go to the Windows Control Panel and select Administrative Tools > Services
b. Find the Ansoft RSM Service and make sure its status says Started. If the RSM Service is not running, try to start it by right-clicking on the service and choosing Start. If it still does not start, then check the username/password combination listed in the Log On tab of the service properties.

5. Make sure that the user listed in the service is an administrator.

6. Make sure that the COM engine is registered with the Ansoft RSM Service:
a. From the Windows menu, select Start > All Programs > Ansoft > Designer > Register with RSM

If none of the above are able to fix the problem, please contact Ansoft Technical and Installation Support as described in the Designer Release Notes.

2. Confirm that you have not changed the Ansoft Service Port from the default setting of 32958 via Tools > Options > General Options > Analysis Options. If the Service Port has been altered, change it back to 32958, then restart Designer and try to solve again.

3. Make sure that the local machine is able to contact the RSM port on the remote node:
a. Open a command prompt on the local machine and type telnet <remote node name> 32958. If the terminal appears to be hanging, then the connection was successful.

4. Check to make sure that the Remote Simulation Manager is running:
a. Go to the “rsm” subdirectory of the Ansoft Remote Simulation Manager installation directory, <RSM_installdir>/rsm
b. Type ./ansoftrsmservice status
c. If the status query indicates that the service is stopped, type ./ansoftrsmservice start

5. Make sure that the COM engine is registered with the Ansoft RSM Service:
a. Type ./RegisterEnginesWithRSM.pl status from within the Designer installation directory.
b. If the status query indicates “Not registered”, type:
      ./RegisterEnginesWithRSM.pl add

If none of the above are able to fix the problem, please contact Ansoft Technical and Installation Support as described in the Designer Release Notes.
