I'm trying to open an Abaqus GUI on a cluster. So far I've done this using:

  • I log in on the cluster using MobaXterm

  • I start a job using:

    qsub -I - X -l nodes=1:ppn=1,mem=32gb

  • I load Abaqus:

    module load abaqus/2019

  • I call the Abaqus GUI:

    abaqus cae

As said, this used to work until the day before yesterday. Now I get the following error when I try this:

Abaqus License Manager checked out the following license:

"cae" from Flexnet server the_server

<15 out of 30 licenses remain available>

FXApp::openDisplay: unable to open display :0.0

Fatal Exception: connect

Abaqus Error: Abaqus/CAE Kernel excited with an error

I've looked around and it seems that somebody else had a very similar problem here, with solutions being posted here (see the figure below). However, the solution specifies '/etc/NetworkManager/nm-system-settings.conf', a file I cannot seem to find (I'm using Windows).

Does anybody know how to solve this issue?

The problem was that

qsub -I - X -l nodes=1:ppn=1,mem=32gb

should be

qsub -I -X -l nodes=1:ppn=1,mem=32gb

(removing the space between - and X)
