<pre wrap="">I would like export in an xdmf format the results of a 1D numerical

1) I would like to visualize a 3D cylinder instead of the line. However,
tube filter is always gray and I cannot use it;

You data is an unstructured grid (even though it is just polylines)
and the tube filter expects a polydata. Try "Extract Surface" to
convert to polydata. I made a note that filters like this should work
with unstructured grids. I will file a feature request.

Dear Berk,<br>
<br>
thank you for the help. With the "extract surface filter" it works
fine. <br>
I agree that would be nice to use directly the tube filter also with
the Polyline objects. <br>
Unfortunately I get confused from this page:<br>

<br>
where it is stated: "For example, if the current object is of type
structured grid, the tube filter will not be active in the 'Filters'
menu since it can be only applied to polylines."<br>

<pre wrap="">2) If I try to use the plot over line filter I get a segmentation fault;
3) If I try to see the grid connectivity with the related filter, I get a
message error.
Probably there is something wrong in my data file, however I cannot find it.
Could you help me, please?

There is indeed something wrong. I suspect that the polyline is
pointing to a point id that does not exist. Keep in mind that ids
start at 0 not 1. Maybe that's the problem?

Yes you are right. I tried a lot of options to make it working, and
before sending the email I forgot to remove the BaseOffset. That is my
fault. Sorry!<br>
