Dear Chetana,

It is difficult to say why the results are not matching. Usually when trying to match data from a publication means understanding all the assumptions made by the authors. That is something you need to carefully check.

Make sure to check that the model you build is exactly as described in the publication.

Hello Sarah,

Unfortunately not via the getcurveresults command. It's simpler:

forces_y = [] # making a list to fill in the force results of phases
forces_y.append(g_o.Phase_1.Reached.ForceY)

by multiplying with 2π my results are not matching with the value of the researcher. kindly help me with this.

Hello Stefanos,

The code you suggested (echo Phase_1.Reached.ForceY) works great. However, when I took it to Python, things got messy. I tried the following codes, and none of them worked. It showed me errors stating that those attributes are not present.

myValue= g_o.getcurveresultspath(g_o.CurvePoints.Nodes.value[0], g_o.Phases[1], g_o.Phase[1]. g_o.ResultTypes.Phase_1.Reached.ForceY

myValue= g_o.getcurveresultspath(g_o.CurvePoints.Nodes.value[0], g_o.Phases[1], g_o.Phases[1], g_o.Phase_1.Reached.ForceY

myValue= g_o.getcurveresultspath(g_o.CurvePoints.Nodes.value[0], g_o.Phases[1], g_o.Steps[1], g_o.Phase_1.Reached.ForceY

Dear Sarah,

I advise you to check the syntax of each command in our Command reference.

The one you suggest in the second line will not work as the getcurveresults does not accept two Phase/Step objects.

You can use instead the getcurveresultspath command which might do what you need.

Hello

I need to replace this line of code to plot a curve within a "For Loop"

uyAs.append(g_o.getcurveresults(g_o.Nodes[0],step,g_o.ResultTypes.Soil.Uy))

Can I use this?

uyAs.append(g_o.getcurveresults(g_o.Nodes[0],Phase_1,Phase_1.Reached.ForceY))

Hello Sarah,

I will explain how you can find it.

Practically you see this value in the Phases window, right? So, that is part of the Phases object.

Therefore, a first step would be to do an

echo Phase_1

This will give you all the information for that phase. If you search you will find the force y you are looking for.

With this you can find that it belongs to the:

Phase_1.Reached

So, another time you can run an echo on that and see the properties that belong where. And there is where you will find the property name.

For 2D CE V21: echo Phase_1.Reached.ForceY
For 2D CE V22: echo Phase_1.Reached.AngularForceY

Dear Chetana,

You can also check a similar example we have: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45556/plaxis-2d-tutorial-01-settlement-of-a-circular-footing-on-sand

Practically you need to multiply by 2π.

Hello Micha, what is the python code to get the reaction force Fy in a 2D model? I could not find it in the reference.

Dear Sir,

This is to inform that I have gone through this blog but the thing is that I want to plot force vs displacement graph of an axisymmetric condition in excel sheet. I have copied the data from PLAXIS 2D model, now the value is given in KN/m but I want it to be in KN now I want to know what meters of length I have to multiply to get the value in KN

The parameters Force Fx, Fy, and for PLAXIS 3D Fz, are the total reaction forces of the applied prescribed displacements in the respective direction.
