[Paraview] [EXTERNAL] Trouble plotting variables

Keeping this thread on the list, so others can see my answer and/or correct me.  :-)

I am pretty sure you have only points, but not 3d cells.  Thus, the lines don’t go through any of your data.  You want a dataset that is solid to do this with.  Download the ParaView data from the Kitware website, load in either can.exo or disk_out_ref.exo and try that.  You can also try plot over line for Sources/ Wavelet.

Alan,

Thank you for your help! I have one more question. Do you have any idea why the "plot over line" does not output data for me? I'm trying to use it to plot displacement over the length of the bar.

Patrick,
I believe you are having multiple problems with your dataset.  Here is what i found:

•         Your dataset appears to be good.  It is a bunch of points (nodes) (cell type vertex).  It displays well.  Read in all of the data, hit apply.  Go to the last time step, then color by Displacement (point).  You see  you have displacement data in your bar.  You can actually see this displacement.  Go back to time step 0, then in the properties tab, change Displacement Magnitude to 1000000 (one million).  Go to last timestep.  (We had to do this because your displacement is tiny in relationship to the length of the bar itself.)  To see the length of the bar, Properties tab, Show Axes.

•         It is difficult, but you can plot a point over time.  The trick is you need to select one point.  Zoom is your friend here.  I rolled the beam around until I could see one point at the bottom.  Then, Select Points On (little icon upper left of the 3d window), and rubber band select a point.  Now, Filters/ Data Analysis/ Plot Selection Over Time.  You see gobs of plots.  Properties tab, slide down, Series Parameters. turn off the plots you don’t want.  I used only displacement magnitude.  You see your displacement.

Hi Everyone,

I am fairly new to paraview and am having a little difficulty. I have a simulation of an elastic bar undergoing a body force and I want to plot it's particle displacement as a function of time. I have followed many tutorials, but my plot does not show any data. The simulation which I'm trying to do this for is found here:

https://drive.google.com/file/d/0B8yl7RuERTNjR3FiZFhPNWVaOTA/view?usp=sharing

Unlike many simulations I have seen run by Paraview, mine object is not a solid body but rather a collection of node points. Could this be why the plot is not working?

Thank you for your help!
