How would we automate the extraction of section forces along a structure (say a column)?

How can we automatically create coordinate systems, construction surfaces + force reaction results scoped to these?

Erik Kostson

Below is one way of doing this (sample script only - change as needed):

model=ExtAPI.DataModel.Project.Model
solution=model.Analyses[0].Solution
constsurf = model.AddConstructionGeometry()
 
for iz in range(1,20,2):
    testCS = model.CoordinateSystems.AddCoordinateSystem()
    testCS.CoordinateSystemType = CoordinateSystemTypeEnum.Cartesian
    testCS.OriginX = Quantity(0,"m")
    testCS.OriginY = Quantity(0,"m")
    testCS.OriginZ = Quantity(iz,"m")
    testCS.PrimaryAxisDefineBy = CoordinateSystemAlignmentType.GlobalX
    surf = constsurf.AddSurface()
    surf.CoordinateSystem = testCS
    forc = solution.AddForceReaction()
    forc.LocationMethod=LocationDefinitionMethod.Surface
    forc.SurfaceSelection=surf
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    mybod=ExtAPI.DataModel.GetObjectsByName('Solid')[0] # change name of Solid part
    selection.Ids = [mybod.GetGeoBody().Id]
    forc.GeometryLocation = selection
    forc.EvaluateAllResults()
    print('MaxTotal: '+ str(forc.MaximumTotal), 'Z-loc: ' + str(testCS.OriginZ))
