Write max vm stress for each part in named selection to file

Erik Kostson

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:

model=ExtAPI.DataModel.Project.Model # refer to Model
analysis = model.Analyses[0]
solution = analysis.Solution
f1=open("D:\\testpartvmstress.txt","w") #open file in user directory change as needed
ns=model.NamedSelections.Children[0] # change named selection as needed / picks the first one in tree, contains all parts to be used below

nIds=ns.Location.Ids
for body in nIds:
    res=solution.AddEquivalentStress()
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    selection.Ids=[body]
    res.Location=selection
    selection=ExtAPI.SelectionManager.ClearSelection()
    res.EvaluateAllResults()
    partname=res.MinimumOccursOn
    parmax=res.Maximum
    f1.write(partname + " , " + str(parmax) +","+ "\n")
f1.close()

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

model=ExtAPI.DataModel.Project.Model # refer to Model
analysis = model.Analyses[0]
solution = analysis.Solution
f1=open("D:\\testpartvmstress.txt","w") #open file in user directory change as needed

for assembly in ExtAPI.DataModel.GeoData.Assemblies:
    for part in assembly.Parts:
        for body in part.Bodies:
            res=solution.AddEquivalentStress()
            selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
            selection.Ids=[body.Id]
            res.Location=selection
            selection=ExtAPI.SelectionManager.ClearSelection()
            res.EvaluateAllResults()
            partname=res.MinimumOccursOn
            parmax=res.Maximum
            f1.write(partname + " , " + str(parmax) +","+ "\n")
f1.close()

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

model=ExtAPI.DataModel.Project.Model # refer to Model
analysis = model.Analyses[0]
solution = analysis.Solution
f1=open("D:\\testpartvmstress.txt","w") #open file in user directory change as needed
ns=model.NamedSelections.Children

for nsi in ns:
    nIds=nsi.Location.Ids
    res=solution.AddEquivalentStress()
    res.Location=nsi
    res.EvaluateAllResults()
    partname=res.MinimumOccursOn
    parmax=res.Maximum
    f1.write(str(nsi.Name) + " , " + str(partname) + " , " + str(parmax) +" , "+ "\n")
f1.close()
