I have downloaded the LS-DYNA student version to run a three-story reinforced concrete building, but I am getting the following error:

 

 *** License problem ***

 Network license:
 *** Error License client cannot find any servers to talk to.

               Servers may be down, not ready, or the wrong version.

The number of nodes and elements is nearly 11,000. 

I would appreciate your support.

Hi Enes, I installed it on my PC and it worked after I restarted the PC. Can you restart and try again?

[Andreas Koutras]

 

Hi Enes, before restarting, open the LS-RUN software, which is installed with the package, and go to License > LS-DYNA License and select the ANSYS license type. Also check the Set. env. box and hit Close. Restart the PC afterwards for the changes to take effect. Let us know if this works.

Hi Andreas,

Thank you for your support. Yes, now it is working fine through LS-Run. I would like to know if it is possible to use the student solver through the LS-DYNA Program Manager or if it can be run only from the LS-RUN. Can you please guide me on how to make it work as I am getting this error:

 

[Andreas Koutras]

I'm not sure if this is supported I have to try.

You can run it though with the LS-DYNA Poweshell that is installed with the package.

[Enes Veliu]

Could you please try and let me know?

[Andreas Koutras]

Hi Enes, I gave the Program Manager a try but without success. The Program Manager was designed for the LSTC license server, while the student package uses the Ansys license. The student package is intended to be run through the LS-DYNA Powershell or LS-RUN, as mentioned in the readme file.

Thank you.

Hello Enes,

We recommend using LS-RUN; the program manager is no longer being maintained.

Hello Enes,

You will find a video tutorial on LS-RUN here:

LS-Run works smoothly. Since I have many analyses (60) to run, I have created 60 cmd files and wish to run them directly by double-clicking on them. However, this is not working and I am having this answer in the message file:

My cmd file contains this script:

Hi Enes,

I put the following two lines in a cmd file and executed the file through the command promt. The two analyses are run sequentially. Once the first analysis completes, the second analysis begins. 

"C:\Program Files\ANSYS 2020R2 LS-DYNA Student 12.0.0\LS-DYNA\lsdyna.exe" i=C:\test\test_eroding_transducer.k o=d3hsp G=d3plot
"C:\Program Files\ANSYS 2020R2 LS-DYNA Student 12.0.0\LS-DYNA\lsdyna.exe" i=C:\test\test_eroding_transducer.k o=d3hspA G=d3plotA

Have you tried this way?

[Enes Veliu]

Thank you Andrea,

The thing is that I can not make it work even with a single model. Could you please take a look at my cmd file and let me know what I may improve?

I am getting the following error:

Hello,

have you specified the Ansys license option through LS-RUN and check the env. var box. After restarting the pc, the license should work.

Then, type the LS-DYNA execution command in a windows command prompt. If this works, copy the same command in a .cmd or .bat file and execute the file. Please do not move lsdyna.exe outside the original installation directory of the student package.

I tested the above in my personal pc and it works well. 

I hope this helps.

[Enes Veliu]

Without understanding why today it is working.
