Search: The search functionality can be activated using the context menu or the shortcut Ctrl+F. Common search options are available, for example case sensitive, match only a whole word, use regular expressions, forward and backward search.

Font settings: The font of the text window can be changed globally using the context menu. The selected font settings are stored in the configuration file and the font size overrides the application base font size.

Parameter: Drop on Parameter pane

Input slots: Drop on Input slots pane

Responses: Drop on Responses pane

Output slots: Drop on Output slots pane

Variables: Drag to Variables to switch the center page and drop on the Variables table

by dragging selection from the Data tab:

by dragging x-axis (also zoomed) from the Visualization tab:

Add variable: Adds a new entry in the variables tab.

Remove variable: Removes all selected entries in variables tab.

Copy variable(s): Writes the selected variables to the clipboard (all as clipboard format, derived as csv-format)

Paste variable(s): Adds the variables contained in the clipboard to

Export variable(s): Exports entries to the following file formats

Import variable(s): Imports entries from the following file formats

Refresh values: Re-reads the entry values.

Resize column to contents: Resizes the view to the current data.

Open calculator: Opens the calculator editor dialog.

  - Adds an environment variable to the list.

  - Removes the selected environment variable. The override for a default environment variable is removed or the variable entry is removed entirely if it does not exist in the default environment.

Default environment - Sets the conditions for the default environment variables.

Prepend project directory and its bin subdirectory to PATH - When selected, two directories are inserted in front of the PATH variable. For example, if your project path is C:\mypath, the variable PATH will be PATH = C:\mypath; C:\mypath\bin; C:\Windows instead of PATH = C:\Windows

Delay before execution: Configures a delay before a process is started. This delay also works as a minimum delay for multiple parallel process starts.

Maximum execution runtime: If a process takes longer than this number of seconds to execute, the run is counted as failed. The process is terminated automatically if maximum runtime is exceeded.

Maximum simultaneous executions: Defines the maximum number of parallel runs. This value may be limited in the configuration file by the parameter IM_DegreeofParallelism .

Designs per execution: Defines the number of designs that will be sent to each process at once.

When selected, activates the launch of a single process for multiple designs. The process node creates a file with designs to be calculated and provides the following environment variables for the executing script:

If this option is enabled, the environment variables OSL_DESIGN_NO, OSL_DESIGN_NAME, and OSL_DESIGN_DIR are not available.

An example implementation for the script in process node:

REM This is a Windows batch script (*.bat)
copy ..\..\..\py\run_multi_cpfunc.py
python run_multi_cpfunc.py %OSL_DESIGNS_BASE% %OSL_DESIGNS_LIST%

An example code snippet to process the designs:

# This is the Python script "run_multi_cpfunc.py"
...
basedir=normpath(sys.argv[1]) # base directory
listfile=normpath(sys.argv[2]) # path of the file containing the listing of design folders
for folder in listfilereader(listfile):
    pd=myreader(join(basedir,folder,'inp_cpfunc.txt')) # pd stands for parameter dictionary
    results={'Y': 0.5*pd['X1']+pd['X2']+0.5*pd['X1']*pd['X2']+5*sin(pd['X3'])+0.2*pd['X4']+0.1*pd['X5']}
    mywriter(join(basedir,folder,'out_cpfunc.txt'),results)
...

Ignore process exit code: When selected, ignores the process exit code, avoiding problems if the code is not evaluable.

Execute through command shell: When selected, interprets the command line or the script as a shell command. When cleared, the process is started at the operating system level.

Python environment: Specifies the type of Python environment to use. The default value is optiSLang Python.

You can select different Python environments that are installed on the system, for example, Python 3.5.64 bit or Anaconda 3.5 64 bit.

Additional Python environment can be made available by adding the location to the PATH environment variable or to the optiSLang.ini configuration file.

Python Script node: An executable file (*exe) is required. This node supports both 32 bit and 64 bit Python.

Python node: A 64 bit Python environment is required as only shared libraries (*.dll, *.so) are supported.

optiSLang's Python can be extended with additional packages.

Auto-save behavior: Select one of the following options:

The project, including the database, is auto-saved (depending on defined interval) after calculating this node/system (either when the calculation succeeds or fails).

Read mode: When selected, the node does not execute, but forwards outputs (files).

Distinct working dir: When selected, creates an extra directory in the design directories for calculations.

Retry execution: When selected, retries a node execution if it failed. Set the following options:

HPC licensing for parametric variations: When selected, forwards the HPC licensing information to the process environment variables.
