    DPF can retrieve nodal stresses directly: Example Node ID - 278

    import mech_dpf

mech_dpf.setExtAPI(ExtAPI)
import Ans.DataProcessing as dpf

dpf.DataProcessingCore.LoadLibrary("math", r"C:\Program Files\ANSYS Inc\v211\aisol\bin\winx64\Ans.Dpf.Math.dll")

ds = mech_dpf.GetDataSources(0)

s1_nodal = dpf.Operator("S1")
s1_nodal.Connect(4, ds)
node_scoping = dpf.data.Scoping([278], dpf.enums.location.nodal)  # Node ID and location
s1_nodal.Connect(1, node_scoping)
nodal_stress = s1_nodal.GetOutputAsFieldsContainer(0).GetFieldByTimeId(1).Data[0]
print nodal_stress
