[Paraview] First trial file does not work-help!

[Emrah Ersan Erdogan]

You are a life-saver, literally. That would not have occurred to me for a long time believe me.

As a final step, in the first piece I want to create only the geometry and in the second piece some points (these are gauss points actually) and with some data.
The problem is, paraview does not see “strain” when it is defined as given below. However, if I swap the point dataset to the first piece it works: on the wrong points of course.
And second, it is apparently not possible to show the geometry and point values at the same time. Do you think I need to define two separate files and "light them up" separately on main paraview screen?

Thank you a lot again. I think this will conclude my problem entirely.

Many text editors use a “smart quotes” feature that replaces the straight quote to a bent open or closed quote. The VTK reader only accepts the straight quotes (ASCII character 34).
