Good evening!

So I just finished making some up grades to my computer (new case, motherboard, and GPU unit) and was expecting ansys to be just as fast if not faster than before, but the exact opposite has happen and the program has greatly slown down. Its been taking 10-15 minutes just to update one component from an ACP Pre module which use  to take less that 30 seconds? I have noticed this even that I have been experiencing a lot of "(DP 0) Connection to peer closed unexpectedly while receiving data.", ''(DP 0) Not connected to a license server for licensing actions.", and another message that would say something like, "licensing server to X amount of seconds to respond."

Not sure if these thing are related, but does anyone have any ideas why my computer or program is running so unusually slowly? 

Thanks!

Hi Harry,

It sounds like you may have a network communication issue/delayed between your machine and the license server machine. Can you open up CMD Prompt , then ping the server and post the output of it here ?

Thanks,

Win

Hey Win,

how does one ping the server from command prompt?

thanks

Hi Harry,

Let's take a step back.

Are you using Ansys student version (free license) or academic (paid license) version ?

Because I was assuming that the latter is the case for you.

 If the former is the case, you may have issue pinging your own hostname 

ping %COMPUTERNAME%

 

but if the latter, please launch Client ANSLIC_ADMIN Utility  View Status  Display License Status  Write to File , and post the content of it .  (Also, please observe how long it takes for it to show the license status)

Thanks,

Win

I'm using and academic license, and sorry but I got a little confused with what you want me to do. Which scenario should I follow? 

tsiriaks posted this 4 days ago

Try this

launch Client ANSLIC_ADMIN Utility  View Status  Display License Status  Write to File , and post the content of it .  (Also, please observe how long it takes for it to show the license status)

Thanks,

Hey Win,

Here is what I got out of that:

Feb 11, 2019 20:44: Attempting to display the license status...

  

====================================================================================================

DISPLAY THE LICENSE STATUS:

 

ANSYS Licensing Interconnect path = 2325@engr12lic.eos.ncsu.edu

I see an error exist

Yea, this error is from the fact that you can't communicate with certain port on the license server. This however isn't related to the ports used for license checkout. So, we can leave it like this at this time. Can you post the output of this command in the CMD Prompt

ping engr12lic.eos.ncsu.edu -4

Here you go Win,

This is what I got

tsiriaks posted this 4 days ago

The ping is quite slow but not that slow to make you see the issue "licensing server to X amount of seconds to respond."

How often do you see that issue (like every time, or just some time) ? 

Please post the screenshot of the content of this folder (assuming default install location) C:\Program Files\ANSYS Inc\Shared Files\Licensing\winx64

Thanks,

Win

assuming this is what you wanted to see? also this happens from time to time, I notice the program running the most slow when I go to update or build a solid model from an ACP module.

tsiriaks posted this 3 days ago

Yes, that's what I wanted to see. This seems fine.

 

Let's do two tests. Try the tests one-by-one in this order

 

1. Turn off Firewall or any security/anti-virus software.

 

If that doesn't help, try

 

2. Install local License Manager (Note: You need admin rights on most of these steps)

- Go to https://support.ansys.com/AnsysCustomerPortal/en_us/Downloads/Current+Release   , then Tools -> download the ANSYS License Manager package

- Install this, then launch the ANSYS License Management Center -> Specify License Manager Run Mode -> select the second radio button "Run the ANSYS Licensing Interconnect without FlexNet" -> back to the View Status (main page) , you should see three items listed here, where the first two say 'running' , and the last one says 'not applicable'

- Launch Client ANSLIC_ADMIN Utility with 'run as administrator -> Specify the License Server Machine -> Add Server Machine -> Fill out your computer hostname , and click "OK" -> You should now see two machines listed in here , select your own machine, then click "Move up" to make sure your own is at the top of the list.

Try using software regularly and see if this makes any differences.

Thanks,

Win
