What is the value of force in KN generated when some prescribed displacement is given. i.e. value of Fy in KN

Question

Micha van der Sloot · Answer

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

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 2&pi;.

Stefanos Papavasileiou · Answer

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 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.

Stefanos Papavasileiou · Answer

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)

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.
