Configuring the aqs.env Environment File

The default aqs.env file is installed with the Abaqus Simulation Engine in the following location:

install_root/platform/SIMULIA_specifics/site/aqs.env

The aqs.env file uses a simple parameter="value" format to define various parameters.

Important: When defining paths in the aqs.env file, use the UNIX forward slash (/) syntax on all platforms.

Most of the parameters should not be modified from their default settings. However, you may need to adjust the following parameters to account for your local installation environment:

basedir_servant

This parameter specifies the directory in which simulations are performed. For execution on an Abaqus Simulation Engine cluster, this directory must be shared among all execution hosts. Large amounts of data may be written to this directory, so you may need to change the default setting if space requirements are an issue.

Simulations are performed under the account of the user who started the server monitor process (see Configuring the Server Monitor). The default setting for the basedir_servant parameter is the home directory for this user. If you change the default directory, the server monitor user must have write permissions in the new directory.

Important: On Windows HPC, the home directory typically is not shared among all machines in the cluster, so the default setting for the basedir_servant parameter does not work. To define a directory that is common on all machines in a Windows cluster, you should use UNC file paths to specify a share; for example: basedir_servant="//share_host/path"

abaqus_lm_licensefile

This parameter indicates the location of the Abaqus FLEXnet license server host. See Licensing Requirements for more information.
