Export and save stress components to a file

There are many ways of doing this (e.g., APDL, DPF, Mech scripting, etc.).

One way of many possible is shown here. The mechanical script below, creates these results and saves them both in separate files, and in one single file.

solution = ExtAPI.DataModel.Project.Model.Analyses[0].Solution
normal_stressx = solution.AddNormalStress()
normal_stressx.NormalOrientation = NormalOrientationType.XAxis
normal_stressy = solution.AddNormalStress()
normal_stressy.NormalOrientation = NormalOrientationType.YAxis
normal_stressz = solution.AddNormalStress()
normal_stressz.NormalOrientation = NormalOrientationType.ZAxis
shear_stressxy = solution.AddShearStress()
shear_stressxy.ShearOrientation=ShearOrientationType.XYPlane
shear_stressxz = solution.AddShearStress()
shear_stressxz.ShearOrientation=ShearOrientationType.XZPlane
shear_stressyz = solution.AddShearStress()
shear_stressyz.ShearOrientation=ShearOrientationType.YZPlane
solution.EvaluateAllResults()
##separatefiles
normal_stressx.ExportToTextFile("D:\mysx.txt")
normal_stressy.ExportToTextFile("D:\mysy.txt")
normal_stressz.ExportToTextFile("D:\mysz.txt")
shear_stressxy.ExportToTextFile("D:\mysxy.txt")
shear_stressxz.ExportToTextFile("D:\mysxz.txt")
shear_stressyz.ExportToTextFile("D:\mysyz.txt")

    #print(node)
