    the below code extracts Von-Mises on node 1: Please change the motion path if necessary.

    import clr, sys,os
sys.path.append(r'C:\Program Files\ANSYS Inc\v221\Motion\bin')
clr.AddReference('System.Collections')
from System.Collections.Generic import List
clr.AddReference('VM.Post.API.OutputReader')
from VM.Post.API.OutputReader import *
analysis = ExtAPI.DataModel.Project.Model.GetChildren(DataModelObjectCategory.Analysis,True)
motion_an = filter(lambda x: x.SolverName == 'ANSYSMotion@ANSYSMotion', analysis)[0]
work_dir = motion_an.WorkingDir
filePath = os.path.join(work_dir,'file.dfr')
outputReader = OutputReader(filePath) 

parameters = PlotParameters()
paths = List[str]()
parameters.Target = "Solid/Node/1"
paths.Add("Top Stress/VonMises")
parameters.Paths = paths

results = outputReader.GetCurves(parameters)


for plot in results :
   print("Time ,", plot.Key)
   for value in plot.Value :
      print(value)
