The image do not say anything, not any error message appear in the image. Post here the text, simply copy & paste.
To take a look to the NX NASTRAN solver simply open the *.F06 file located in the same directoy of the *.SIM file and look for FATAL word. This will tell you the reason of the error.
Thanks for the info.
I have attached the .f06 file pic with this. The fatal error displayed is that of authorisation.
But, i should inform you that Nastran is working fine on other machines. That should point us that the license issue is only with the machine i am using. Suggestions along this direction would be helpful.
Thanks in advance,
As the message indicates, the .log file would be the best file to look at for this issue. It should be in the same directory as the .f06 file and have the same root name (i.e. 2d2011_sim1.log). It will document the license server being contacted and the licenses being requested.
Specifically, you need to verify the setting of the AUTH keyword. This is typically set in the mast#.rcf file, but it can be specified on the command line. This should point to a valid license file/license server.
