Geometry and Mesh editor won’t start with R19.2

      Hello,


      Please, does anyone have an idea of how to make the geometry and mesh editor start (Fluid Flow - Fluent on WB) on a cluster with Centos 7 OS with R19.2 installed (especially the PSC bridges LM nodes)?.


      We have a similar Cluster but with a less RAM memory, was able to make the geometry and mesh editor start with Centos 7 OS with R19.1 installed but when we tried R19.2, it didn't work.


      Thanks,


      Sam

      Hi,


      Please see this stackoverflow thread:


      https://stackoverflow.com/questions/23494103/version-cxxabi-1-3-8-not-found-required-by


       


      Can you also post the output from:


      strings /usr/lib/libstdc++.so.6 | grep GLIBC


       


      Also please post the output from:


      cat /etc/*release*


       


      And finally the output from:


      glxinfo | grep OpenGL


       


      Thank you,


      Jake

      Dear Jake,


       


      My campus HPC:

      Hi Sam,


      Thank you for the additional information.


      I assume the "campus HPC" is the one that doesn't work correct?


       


      There seems to be a few different issues here.


      The first is your LD_LIBRARY_PATH probably does not included the needed directories for GLIBC:


      Try this before launching an ansys application:


      export LD_LIBRARY_PATH=/usr/local/libusr/libusr/local/lib64usr/lib64


       


      Next there is an issue with the software rasterizer swrast_dri.


      What kind of graphics card is installed on that machine?


      If NVIDIA, just install the nvidia drivers from their website.


       


      If not, please try installing the following:


      mesa-dri-drivers


      mesa-libGL


       


      If that doesn't help then run:


      export LIBGL_DEBUG=verbose


      glxgears


       


      Thank you,


      Jake

      Dear Jake,


                       How can we get PSC HPC to start FLUID FLOW (Fluent) schematics (geometry and mesh editor) with R19.2?


      Thank you,

      Hi Sam,


      Did you try what I mentioned in the previous post?


       


      Thank you,

      Hello Jake,


                       I thought you meant the solution is for the campus HPC?


      Please can you rewrite the Export Library line again without the smiley ?


      Thanks,


      Sam

      Hi Sam,


      Which of the two example that you provided are NOT working?


      The Export command is:


      export LD_LIBRARY_PATH=/usr/local/libusr/libusr/local/lib64usr/lib64


       


      I don't know if the forum will allow me to post it and not convert the : and / to a smiley.


      If the above line is still converted to smiley faces, just replace the smiley with a colon and a forward slash.


       


      Thank you,


      Jake

      Hello Jake,


                       This was the error obtained after changing export LD_LIBRARY Line on PSC HPC:

      Hi Sam,


      For the first error, is the following environment variable set:


      SLURM_GTIDS


      If so, unset it.


       


      For the second issue see this link:


      https://ubuntuforums.org/archive/index.php/t-2161981.html


       


      Can you tell me what graphics card is installed?


      What kind of graphics card is installed on that machine?


       If NVIDIA, just install the nvidia drivers from their website.


       


       In the current configuration it does not appear you have 3D capabilities on that machine, which will be required to run the software.


      Please get glxgears running first and try the Ansys software again after that.


       


       


       


       


      Thank you,

      Additionally please see:

      If you are using an nvidia card on that machine, please make sure the nouveau driver is disabled, and the nvidia drivers are installed from the nvidia website (not from what is packaged with the OS):

      Dear Jake,


                       I did tried option one before you gave that and also after, it didn't work.


      For Option 2: I forwarded that to the appropriate party(with administrative right on the PSC cluster). I think he tried it and didn't work also. I even convinced the administrator to install R19.1 and to model it like UWM Cluster and that also didn't yield any fruit.


      So what's the way forward?


      My suggestion: Why not  dedicate someone to take a look at the PSC cluster via my end(user) or contact the administrators and diagnose/troubleshoot the problem like you guys did with my campus cluster (UWM cluster). 


      Thanks,


      Sam
