CFD Online Discussion Forums - Cortex Connection Broken

Hey guys,
I am running a 3d calculation with Fluent and exporting the data as a PATRAN file. After a series of lines which read as follows: [CODE]vis_StateSetData: ierr= 1
SYS_ERROR_VALUE Argument with an improper value
id= 2463596 [\CODE]

I get the following error and the calculation stops

Code:

Closing library "C:\PROGRA~1\ANSTS~1\v145\fluent\fluent14.5.7\vki\win64\devtools4.0.2.dll"...done

........

.........



Writing PATRAN nodal results file.....

    computing pressure at nodes....

Message from Cortex process = = >Connection with host is broken. It may have crashed

MPI Application rank 0 exited before MPI_finalize() with status -1

My question is, is this a licence issue that we don't have the required resource, or is it some other problem that I need to alter settings?

If you could help it would be great
