Software Rendering Mode for Fluent Launcher

When running Fluent from inside ANSYS Workbench on Linux. Hardware graphics rendering can fail and the Fluent application failed to start. This error can sometimes be prevented by switching to the software rendering mode. There are 2 approaches

Before Running Workbench, you may want to put this in your BASH Shell

% export HOOPS_PICTURE=x11/lin

In C Shell

% setenv HOOPS_PICTURE x11/lin

If you are using Fluent Launcher

Steps:

Open a Fluent set of cells
Right Click the Fluent setup cell and choose, edit
In the resulting Fluent launcher, choose +, Show More Options
Select the Environment tab
Add the following entry
HOOPS_PICTURE=x11/lin

Licensing error while opening ANSYS Fluent Meshing

The usage of Fluent was smooth. But when I launched the Fluent (Fluent with Meshing)

I’ve got this error. “No license is available at this time”

Taking a look at ANSYS Learning Forum, According to the forum (Licensing error while opening ANSYS Mechanical) “That error message would appear when there is another operation going on that won’t allow the license to be shared , such as meshing or solving, etc.

To resolve the issue:

  1. Execute the command “/usr/local/ansys_inc/v195/commonfiles/tools/linx64/ansyslm_relutil -userprefs

You should see the dialog box.

You have to go to the bottom of the dialog box “When using Workbench, would you like to”, Use a separate license for each application

Finally, close the application and restart. The issue should go away.

MPI related Errors for ANSYS-20.1

One of my users was facing the issues when running ANSYS-20.1 Fluent

There were a few steps that we took to resolve the issues. Do look at the generated logs which will give lots of information. If you are using the PBS-Professional. your fluent script may look like this.

fluent 3ddp -g -t$nprocs -mpi=ibmmpi -cflush -ssh -lsf -cnf=$PBS_NODEFILE -pinfiniband -nmon -i $inputfile >& $PBS_JOBID.log 2>&1
  • Do note that “-cflush” and that it should be placed after the -mpi flag. From our observation, if the -cflush is placed before -mpi, it seems to initiate the flush, but another error would be generated.
  • Make sure you choose the right mpi parameter.
