    In short using mech scripting, we would like to write e.g., max vm stress for each part in named selection to a text file.

      One way of doing this is presented below:

      1. model=ExtAPI.DataModel.Project.Model # refer to Model
      2. analysis = model.Analyses[0]
      3. solution = analysis.Solution
      4. f1=open("D:\\testpartvmstress.txt","w") #open file in user directory change as needed
      5. ns=model.NamedSelections.Children[0] # change named selection as needed / picks the first one in tree, contains all parts to be used below
      6.  
      7. nIds=ns.Location.Ids
      8. for body in nIds:
      9.     res=solution.AddEquivalentStress()
      10.     selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
      11.     selection.Ids=[body]
      12.     res.Location=selection
      13.     selection=ExtAPI.SelectionManager.ClearSelection()
      14.     res.EvaluateAllResults()
      15.     partname=res.MinimumOccursOn
      16.     parmax=res.Maximum
      17.     f1.write(partname + " , " + str(parmax) +","+ "\n")
      18. f1.close()
      19.  

      If we want to do it for all parts in Mechanical (so no need to add relevant parts in Named Selection):

      1. model=ExtAPI.DataModel.Project.Model # refer to Model
      2. analysis = model.Analyses[0]
      3. solution = analysis.Solution
      4. f1=open("D:\\testpartvmstress.txt","w") #open file in user directory change as needed
      5.  
      6. for assembly in ExtAPI.DataModel.GeoData.Assemblies:
      7.     for part in assembly.Parts:
      8.         for body in part.Bodies:
      9.             res=solution.AddEquivalentStress()
      10.             selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
      11.             selection.Ids=[body.Id]
      12.             res.Location=selection
      13.             selection=ExtAPI.SelectionManager.ClearSelection()
      14.             res.EvaluateAllResults()
      15.             partname=res.MinimumOccursOn
      16.             parmax=res.Maximum
      17.             f1.write(partname + " , " + str(parmax) +","+ "\n")
      18. f1.close()

      Finally if we want to loop over named selections and get the maximum in each named selection:

      1. model=ExtAPI.DataModel.Project.Model # refer to Model
      2. analysis = model.Analyses[0]
      3. solution = analysis.Solution
      4. f1=open("D:\\testpartvmstress.txt","w") #open file in user directory change as needed
      5. ns=model.NamedSelections.Children
      6.  
      7. for nsi in ns:
      8.     nIds=nsi.Location.Ids
      9.     res=solution.AddEquivalentStress()
      10.     res.Location=nsi
      11.     res.EvaluateAllResults()
      12.     partname=res.MinimumOccursOn
      13.     parmax=res.Maximum
      14.     f1.write(str(nsi.Name) + " , " + str(partname) + " , " + str(parmax) +" , "+ "\n")
      15. f1.close()
