Message definition (Ansys)
Ansys allocates 1024 MB total memory and 1024 MB database memory by default for APDL jobs. These values can be manually specified (or changed) by adding arguments <code>-m 1024</code> and/or <code>-db 1024</code> to the mapdl command line in the above scripts. When using a remote institutional license server with multiple Ansys licenses, it may be necessary to add <code>-p aa_r</code> or <code>-ppf anshpc</code>, depending on which Ansys module you are using. As always, perform detailed scaling tests before running production jobs to ensure that the optimal number of cores and minimum amount memory is specified in your scripts. The <i>single node</i> (SMP Shared Memory Parallel) scripts will typically perform better than the <i>multinode</i> (DIS Distributed Memory Parallel) scripts and therefore should be used whenever possible. To help avoid compatibility issues the Ansys module loaded in your script should ideally match the version used to to generate the input file:

Par défaut, ANSYS alloue aux tâches APDL 1024Mo de mémoire totale et 1024Mo de mémoire pour les bases de données. Ces valeurs peuvent être définies manuellement (ou modifiées) avec l'ajout des arguments -m 1024 et/ou -db 1024 sur la dernière ligne de commande des cscripts ci-dessus. Si vous utilisez à distance un serveur de licences de votre établissement qui a plusieurs licences ANSYS, il pourrait être nécessaire d'ajouter des arguments comme -p aa_r ou -ppf anshpc.

As always perform detailed scaling tests before running production jobs to ensure the optimal number of cores and minimum amount memory is specified in your slurm scripts. The single node SMP (Shared Memory Parallel) script will perform better than the multiple node DIS (Distributed Memory Parallel) script and therefore should be used whenever possible. To help avoid compatibility issues the ansys module loaded in your slurm script should ideally match the version used to to generate the input file:
