<p>Hi!<\/p><p>I hope you are all doing well. I am posting because I am tying to run an eigenmode simulation using a slurm script on a high performance computing cluster, but I am running into this error (the image is from the log file that is automatically created after submitting the slurm script):<br><br><br><br>I tried to delete the asol file and rerun, but the issue persists. The simulation I am trying to run is a test, so it is just a box with vacuum assigned as the material (pretty simple to run so I am not hitting any ram limits or any storage limits). When I tried to run this in interractive mode, it works fine, so I do not think there is something wrong with the file or with my permission to store the solutions on the working directory. <br>If any of you had any ideas on what else to try, I would really appreciate it. Thank you in advance!<br><br><br>Here is my script:<br><br><\/p><p>#!\/usr\/bin\/env bash<br>#SBATCH –job-name=HFSS_Simulation<br>#SBATCH –nodes=1                     # Number of compute nodes<br>#SBATCH –ntasks-per-node=16           # Number of tasks (cores) per node<br>#SBATCH –time=04:00:00                # Maximum runtime<br>#SBATCH –partition=small             # Partition to submit to<br>#SBATCH –output=hfss_output_%j.txt    # Output file<br>#SBATCH –error=hfss_error_%j.txt      # Error file<br>#SBATCH -A PHY23031<br>#SBATCH –mail-type=ALL<br>#SBATCH –mail-user= user email<\/em><\/p><p>export TMPDIR=\/scratch1\/username<\/em>\/tmp<\/p><p>mkdir -p $TMPDIR<\/p><p># Load Ansys HFSS module (or set environment variables for Ansys if TACC doesn’t have a module system)<\/p><p>module load ansys\/2022R2                  # Adjust based on available versions# Set up the environment to run HFSS<\/p><p>export HFSS_EXE=”\/home1\/apps\/ANSYS\/2022R2\/AnsysEM\/v222\/Linux64\/ansysedt”   # Path to the HFSS executable<\/p><p># Path to your HFSS project file (“.aedt”)<\/p><p>PROJECT_FILE=”\/home1\/username<\/em>\/batch_test\/project_1.aedt”    # Create a temporary directory for the job on the compute node<\/p><p>DESIGN_NAME=”design_1″<\/p><p>WORKDIR=$SLURM_SUBMIT_DIR\/$SLURM_JOB_ID<br>mkdir -p $WORKDIR<br>cd $WORKDIR    # Copy the project file to the working directory (optional)<br>cp $PROJECT_FILE $WORKDIR    # Run HFSS with MPI across multiple nodes<br>mpirun -np $SLURM_NTASKS $HFSS_EXE -ng -BatchSolve $DESIGN_NAME:Nominal $PROJECT_FILE<\/p><p># Clean up (optional)<br>cp -r $WORKDIR\/* $SLURM_SUBMIT_DIR<\/p><\/p>\n","protected":false},"template":"","class_list":["post-393370","topic","type-topic","status-publish","hentry","topic-tag-ansys-hfss","topic-tag-ansys-hpc-2","topic-tag-batch-script"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
