CFX-Pre Failed to Connect to Workbench


CFX on the Windows operating system cannot start CFX-Pre. Or when CFX-Pre is started outside Workbench it takes a long time to start.

*Resolution*
This problem is license related and often happens when the license server is located remotely The following sequence of steps should be followed to fix this issue:

1.Set the Environment Variable : CFX_DISABLE_PHYSICS_LICENSING = 1
2.Delete all unused License Servers in the /ansys_inc/shared files/licensing/ansyslmd.ini.
3.Go to the C:Windowssystem32driversetc directory. Open the hosts file and add a line giving the IP address and Host name of the license server.

*Additional Resolutions*
1.If the Windows Firewall is turned on you might need to add the following exceptions, cfx5pre.exe, cfx5post.exe and cfx5Solve.exe. These executables are located in C:Program FilesAnsys Incv110CFXbin.
2.Delete .cfx folder in C:Documents & Settings(USERID)
