Our LSDYNA network license was operational up until few weeks ago and then stopped. We were'nt notified until recently, so the synopsis is as follows:

 

LSDYNA not Working

Not sure when, but out LSTC windows service stopped functioning and we were just notified. Manual start of the service fails, so clients are unable to connect. I tried a fresh install of the license manager in a new directory, but service still fails. The LSTC log file displays the following:

*********************************************************************

Additionally, when I try to start the service from the console,

Timed out trying to start the service
Using config file c:\lsdyna2024\server_data
Error: Could not open configuration file
Error: Could not open license file c:\lsdyna2024\server_data

 

Since playing around with this further, I've now run into an additional problem. I tried a completely fresh install, removed the service, reinstalled in a new directory, only now when I try to run the license manager utility I get a Visual Basic error.......unable to get past that..... now the utility is completely non functional

Hello Kyle,

I don't think you are using the free Ansys software are you? If so, this post is in the wrong channel.

You are getting the following error message:

ERROR: the host id(s) of this machine ( 7D76C756 4699DD69 )
not found in the license file C:\LSDYNA2024\server_data

 

This means that the host ID of the LSTC licence server does not match the host ID in the LSTC license file (server_data). The entire strings of characters must match in the SERVER lines of both the LSTC_SERVER_INFO generated on the license server and the server_data files (not just the first few characters must match, but all of them).

So, either you are trying to use the license file (server_data) on a different license server, or the host ID of the license server as changed. This can happen, especially if the license server is a virtual machine.

You will need a new LSTC license file. Generate the LSTC_SERVER_INFO file on the license server and send this file to your Ansys account manager to get a new license file. You will find the procedure for Windows here:

Let me know how it goes.
