Here is a minimum working script for you, import openseespy.opensees as ops import openseespy.preprocessing.DiscretizeMember as opsdm import matplotlib.pyplot as plt ops.wipe() ops.model('basic', '-ndm', 2, '-ndf', 3) L = 4. A = 2.e-3 I = 1.6e-5 E = 200.e9 Ep = {1: [E, A, I]} ops.node(1, 0., 0.) ops...

This is a great explanation by Dr. Scott.

Have you defined all the parameters needed for the "DiscretizeMember" command? It looks like you haven't defined "Integration Tag" for the element. Also, this command may not work for the "elasticBeamColumn" element. You should use the "forceBeamColumn" or &qu...

Could you please create a new issue here? This has to do with how "ops_vis" handles its calculation. --> https://github.com/zhuminjie/OpenSeesPy/issues

In general, I would only prefer OpenSees calculations and not ope_vis or Get_Rendering modules.

In order to get displacements at all the intermediate points, you need to divide the beam into multiple elements. Use "DiscretizeMember" from openseespy.preprocessing module.

PVD recorder does the same thing and you can visualize the results using Paraview.

You could use OpenSeesPy visualization library to interactively view your Tcl models and output. Here is an example.

This is a bug in matplotlib due to compatibility with Chromium based web browsers (Google Chrome, Edge explorer). A trick to save the figure is
1) stop the interaction on the generated plot by clicking on the blue button.
2) right-click on the plot image and save it.

[/quote] I have tried what you suggested but still the answer is the same as previous. This time also Opensees has not considered the load I applied after converting it to mass. [/quote] You have to have a conversion both ways. In this case, you want the load to be converted in to a mass. For exampl...

OpenSees will not convert load to mass (or the other way) for you. You could assign load as a function of the mass so you don't have to worry about it.
For example,

load 42 0 0 [expr -$massCol*$g] 0 0 0

You could use post-processing commands in OpenSeesPy (Python) to visualize mode shapes of your Tcl models. See the links here, 1) A little tutorial on how to combine OpenSeesPy post-processing commands with Tcl model. https://anuragupadhyay.weebly.com/openseespy-visualization-for-opensees-tcl.html h...

It is working fine for me. Try re-installing the tcl/tk.
