### Re: Learning Openseespy through a very simple example [good drift for beam discretization, code still fails]

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...

### Re: Learning Openseespy through a very simple example [beam discretization still unsolved]

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 "dispBeamColumn" element with an Elastic se...

### Re: Diagram (P,V,M) values partially discrepant with reactions

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.

### Re: Learning Openseespy through a very simple example

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.

### Re: VTK recorder

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

### Re: 2D Model Display

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

### Re: Plot is not downloadable

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.

### Re: Eigen Value Analysis

[/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.

### Re: Eigen Value Analysis

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

### Re: Eigen Analysis Result 3D Model

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...

### Re: OpenSees2.4.5-x64.exe

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