How can we automatically export far-field directivities from a harmonic acoustic analysis when performing a parametric study?

Erik Kostson

Below is one way of doing that (using python code object - after post). It assumes that we have a harmonic acoustic analysis with a results object called Far-field Maximum Scattered Pressure.

Script:

def after_post(this, solution):# Do not edit this line
    """
    Called after post processing.
    Keyword Arguments : 
        this -- the datamodel object instance of the python code object you are currently editing in the tree
        solution -- Solution
    """

    # To access properties created using the Property Provider, please use the following command.
    # this.GetCustomPropertyByPath("your_property_group_name/your_property_name")

    # To access scoping properties use the following to access geometry scoping and named selection respectively:
    # this.GetCustomPropertyByPath("your_property_group_name/your_property_name/Geometry Selection")
    # this.GetCustomPropertyByPath("your_property_group_name/your_property_name/Named Selection")
    myfile='D:\maxprefarfield.txt' # change as needed
    ffr=ExtAPI.DataModel.GetObjectsByName('Far-field Maximum Scattered Pressure')[0]
    ffr.Activate()
    ffr.ExportToTextFile(myfile)

to get the current design point (say in order to include it in the saved file name use this:

import wbjn
dpn=wbjn.ExecuteCommand(ExtAPI,"returnValue(a+Parameters.GetActiveDesignPoint().Name)",a="DP")
