Creating a new discussion as I have not had a resolution on an earlier issue. Also editing to add that we have tried this with a newer version of Ansys (2020 R1) with similar result so it appears to be system related.
I am using icemcfd with Ansys 19.3. When I launch icemcfd it is very slow to load, sometimes taking up to 3-5 minutes.
The OS is CentOS 7.
I am using environment modules to load the software. This is the environment module.
set topdir /home/ansys2019r3/
set version v195
prepend-path PATH $topdir/$version/ansys/bin
prepend-path PATH $topdir/$version/Framework/bin/Linux64
prepend-path LD_LIBRARY_PATH $topdir/$version/Framework/bin/Linux64/Mesa
prepend-path PATH $topdir/shared_files/licensing/lic_admin
prepend-path PATH $topdir/$version/home/ansys2019r3/v195/fluent/bin
setenv ANSYS182_DIR $topdir/$version/ansys
setenv ANSYSLIC_DIR $topdir/shared_files/licensing
prepend-path PATH $topdir/$version/fluent/bin
prepend-path PATH $topdir/$version/icemcfd/linux64_amd/bin
setenv ICE_ACN $topdir/$version/icemcfd/linux64_amd
prepend-path PATH $topdir/$version/autodyn/bin
prepend-path PATH $topdir/$version/Framework/bin/Linux64
prepend-path PATH $topdir/$version/polyflow/bin
Once I type in 'icemcfd' it hangs on ICEM_ACN is "/home/ansys2019r3/v195/icemcfd/linux64_amd" and eventually after 5 minutes the software will launch.
Eventually when it does load I get this output on the command line:
LD_LIBRARY_PATH is "/home/ansys2019r3/v195/icemcfd/linux64_amd/lib
Window information: depth = 24
class = 4

can't load font screen14, using variable
can't load font symbol14, using variable
can't load font symbol18, using variable
can't load font symbol24, using variable
Graphics system = OglDL
I am not sure what else to troubleshoot. This is a clean installation. I also have the same issue with an existing install on another CentOS 7 machine. Same version of Ansys.
I have tried it without the environment module and I get the same result.
Thanks for any assistance.February 9, 2021 at 11:39 pmANSYS_MMadoreAnsys EmployeeCould you try without specifying your own LD_LIBRARY_PATH? What is the latency with the license server? Do other applications launch in this environment without issue? This could be graphics related, could you share the results of these commands?nglxinfo -display :0 | grep -i opengl.versionnexport LIBGL_DEBUG=verbose glxgearsnexport LIBGL_DEBUG=verbose glxinfonlspci -vnn | grep VGA -A 12nnvidia-sminnvidia-settings -q NvidiaDriverVersiovidia-settings -q allnnThanks,nMattnFebruary 17, 2021 at 8:21 pmrachael.auchSubscriberArray nThanks for the reply. nTried without specifying our own LD_LIBRARY_PATH, no change. No issues with the license server. Other applications can launch in this environment without any problems. Right now it seems to just be ICEM-CFD. nThis just seems to be domain accounts only that this is affecting as well. This Linux server is joined to a Windows AD domain. Icem-cfd opens just fine for root and also for a local account. I used 'env' to compare the environment variables between my account and a local account as a test, there is no considerable difference. nIn playing around with the icemcfd launch script, default location: /ansys_inc/v195/icemcfd/linux64_amd/bin I commented out the following lines:# (re)set limits for at least OSF1 and AIX41n#if ( id | sed 's/^[^=]*/;s/[( ].*$/' == 0) thenn # root must not unset the limits onn # various operating systemsn# echo 'Hallo root.'n#elsen# set uname_r= uname -r n# set uname_s= uname -s n# if ( $uname_s != Linux && expr $uname_r : B.11* < 4) thenn# unlimitn# endifn#endifnnAnd this seems to have resolved the problem for my domain account and one other. One other person is still having issues however, I need to do some further troubleshooting with that person, but I do not know why that would make a difference but it has cut the time to open the program down to ~5 seconds from 5 minutes. nThis is the output for the commands suggested:glxinfo | grep -i opengl.versionnOpenGL version string: 2.1 Mesa 18.3.4nnlspci -vnn | grep VGA -A 12n0a:03.0 VGA compatible controller : Matrox Electronics Systems Ltd.

While you may see it work, it's unsupported.nViewing 3 reply threads
