My research requires that I use a development version of LS-DYNA, which I receive from ANSYS personnel and update on a semi-regular basis. Last year, my institution’s LS-DYNA license was connected with an LSTC license file, which was appropriately referenced by our supercomputer in a file named LSTC_FILE, which has the following format:<\/div>\n
 <\/div>\n
#LICENSE_TYPE: network<\/div>\n
#LICENSE_SERVER: <port_number>@<host_address><\/div>\n
 <\/div>\n
This LSTC_FILE was (and is) located in the same directory as the development builds of LS-DYNA, and, prior to this year, I was able to run a variety of analyses using thse development versions of LS-DYNA.<\/div>\n
 <\/div>\n
This year we have been unable to connect our valid license files with these development versions of LS-DYNA. Originally, we simply had an ANSYS license file that has LS-DYNA functionality supported, but referencing the appropriate host and port yielded a licensing error. We have now received an LSTC license file (in addition to, but not clearly necessary) to accompany our ANSYS license file and connected this with the original server\/port that hosted our LSTC license last year. We anticipated that this would have solved the problem. However, I am still receiving an error message stating <\/span><\/div>\n
 <\/div>\n
 <\/div>\n
*** License problem ***<\/div>\n
 Network license:<\/div>\n
 <\/div>\n
 *** Error License client cannot find any servers to talk to.<\/div>\n
               Servers may be down, not ready, or the wrong version.<\/div>\n
 <\/div>\n
  <\/div>\n
 *** Error 70022 (OTH+22)<\/div>\n
 <\/div>\n
 <\/div>\n
Nonetheless, ncat commands indicate that the connections on our needed to find both the LSTC and the ANSYS license files are working. Furthermore, basic run commands also appear to work successfully on the non-development version of LS-DYNA that we have installed. I have screenshots demonstrating this, but for privacy reasons choose to not post them here. We have tried modifying our LSTC_FILE with each of the different ports and addresses necessary to refer to these license files, but to no avail. At this point, we are at a loss on how to access the software. <\/div>\n
 <\/div>\n
1. With the change of the year, did a “hello” message necessary to communicate with the license change?<\/div>\n
2. Do we need to modify the format of the LSTC_FILE, or refer to this license some other way?<\/div>\n
3. Should we just be able to use our generic ANSYS license file to run these beta versions of LS-DYNA, or do we need the LSTC license file to run these executables? We have both licenses, and both are being found from our login node, but for some reason the executables are not recognizing these licenses.<\/div>\n
 <\/div>\n
How can we proceed in getting our license issues resolved?<\/div>\n","protected":false},"template":"","class_list":["post-366162","topic","type-topic","status-closed","hentry","topic-tag-buglicensingerror-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
