Say we have a vibro-acoustic models and a FSI surface - named selection called watersteelinter_so_fsi. How can we print the average pressure there for each frequency ?

    Below is one possible way of doing this :

    analysis = Model.Analyses[0]

solution=analysis.Solution

ns = DataModel.GetObjectsByName('watersteelinter_so_fsi')[0]

mypresres=ExtAPI.DataModel.Project.Model.Analyses[0].Solution.AddAcousticPressureResult() # insert Pressure result

mypresres.Location=ns

mypresresname=mypresres.Name

resallset=solution.CreateResultsAtAllSets(mypresres.ObjectId)

fpath = "D:/"
fname = "myaverpres.txt"
f = open(fpath+fname,"w")
for set in resallset:
    #print(set.Name + 'mean pres. : ' + str(set.Average) + ', at freq. :  ' + str(set.ReportedFrequency))
    #write to file as needed
    f.write(str(set.Name) + 'mean pres. : ' + str(set.Average) + ', at freq. :  ' + str(set.ReportedFrequency) +"\n")
f.close()
#mypresres.Delete()
#pd= DataModel.GetObjectsByName(mypresresname)[0]
#pd.DeleteTreeGroupAndChildren()

    and as a Python code (under solution) with an after solve callback:

    def after_solve(this, analysis):# Do not edit this line
    """
    Called after solving the parent analysis.
    Keyword Arguments : 
        this -- the datamodel object instance of the python code object you are currently editing in the tree
        analysis -- Coupled Field Harmonic
    """


    # 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")
    solution=analysis.Solution

    ns = DataModel.GetObjectsByName('watersteelinter_so_fsi')[0]

    mypresres=ExtAPI.DataModel.Project.Model.Analyses[0].Solution.AddAcousticPressureResult() # insert Pressure result

    mypresres.Location=ns
    mypresresname=mypresres.Name
    mypresres.EvaluateAllResults()
    resallset=solution.CreateResultsAtAllSets(mypresres.ObjectId)
    mypresres.Delete()
    fpath = "D:/"
    fname = "myaverpres.txt"
    f = open(fpath+fname,"w")
    for set in resallset:
        #print(set.Name + 'mean pres. : ' + str(set.Average) + ', at freq. :  ' + str(set.ReportedFrequency))
        #write to file as needed
        set.EvaluateAllResults()
        f.write(str(set.Name) + ', mean pres. : ' + str(set.Average) + ', at freq. :  ' + str(set.ReportedFrequency) +"\n")
        set.Delete()
    f.close()
    pd= DataModel.GetObjectsByName(mypresresname)[0]
    pd.DeleteTreeGroupAndChildren()
    pass
