Again, thank you very much

This photo helped me a lot, I was able to solve the problem

Hello again,

You should check in your code what is done at each step (basic debugging). From your code, I cannot really tell what does the phaseorder variable contain. This has to have PLAXIS Output phase objects, e.g. g_o.Phase_1, g_o.Phase_2, etc.

In my case it works fine:

Epsyy_o = []
SigyyE_o = []

for phase in phaseorder:
for step in phase.Steps:
Epsyy_o.append(g_o.getcurveresults(punto, step, g_o.ResultTypes.Soil.Epsyy))
SigyyE_o.append(g_o.getcurveresults(punto, step, g_o.ResultTypes.Soil.SigyyE))

I'm sorry, but tell me:

"AttributeError: Requested attribute 'Steps' is not present"

Dear Andrés,

The Steps object is part of the Phases object. Therefore you can add an extra loop as follows:

for phase in phaseorder:
for step in phase.Steps:
# rest of code

Dear Stefanos Papavasileiou,

Thanks for helping me, this link helped me a lot, but the results are only at the end in the phase, I want results about each step in the phase.

Again, I share part of my code (corrected):

x_i= 0
y_i= medio

punto = g_o.addcurvepoint("stress point", (x_i, y_i))
punto.Identification = "Central"
g_o.update()

g_i.calculate()
g_i.view(shear_phase)

curvepoints_central = g_o.CurvePoints.StressPoints
print(g_o.tabulate(curvepoints_central, "x y"))

Epsyy_o = []
SigyyE_o = []

for phase in phaseorder:
Epsyy_o.append(g_o.getcurveresults(punto, phase, g_o.ResultTypes.Soil.Epsyy))
SigyyE_o.append(g_o.getcurveresults(punto, phase, g_o.ResultTypes.Soil.SigyyE))

with open("ey - Sy'" + ".txt", "w") as file:
file.writelines(["{}\t{}\n".format("Epsyy", "SigyyE_kPa")])
file.writelines(["{:.5f}\t{:.2f}\n".format(Epsyy, SigyyE)
for Epsyy, SigyyE in zip(Epsyy_o, SigyyE_o)])

Dear Andres,

You are on the right path. You select a point but then you use the getresults command which returns results for all stress points. Instead, you should use the getcurveresults command.

You can check an example here: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45450/output-scripting-example-create-curve-data
