You can directly couple an external calculation code in Persalys, provided that the communication with the code is possible using input and output files and that it is executable from a terminal or using the batch mode. A physical model is specifically developed to do so.

The different coupling steps are as follow:

• creation of template input files containing tokens instead of the values to vary
• execution of the external code, based on the input file created from the template file
• reading of the results in one or several output files, written by the external code

Persalys offers various features allowing to simply perform complex coupling:

• possibility to execute several commands in a row
• the outputs of a previous command may be used as inputs for the following commands
• execute the calculations in a temporary configurable work folder
• transfer resources (folders, files) in the work folder
• activate a caching mechanism that allows you to save the already performed evaluations
• directly check the proper configuration of the template input file in Persalys
• check the proper reading of the results via a standard result file
• directly add Python pre or post-treatment in Persalys
• a summary tab will summarizes all the input and output parameters that are globally defined
