Dear Geordie,<br>
<br>
Thank you so much for your prompt reply.<br>
<br>
<ol>
<li>I followed the example in <a class="moz-txt-link-freetext"
href="http://www.geuz.org/pipermail/gmsh/2010/005676.html">http://www.geuz.org/pipermail/gmsh/2010/005676.html</a>
, and it worked fine. However, trying to apply it to my data (from the
GUI) caused Gmsh to crush. I attach the relevant files: post-1c.msh is
the mesh (nodes & elements), post-080.msh are the results (at nodes
& elements) at the 80th iteration, and post-1c.msh.opt is the
options file. Please see it you can draw the temperature distribution
along z and a certain polar angle, 162 degrees say, for e.g., at the 1D
elements Tfluid (views 0 and 8) and the 2D elements Tw (views 19 and
55).</li>
<li>I do not understand the suggestion how to use the "physical
entity" tags to select and unselect parts of the geometry. Can you
please demonstrate it, preferably on the files I had sent?</li>
</ol>
The following questions from my original message were not answered.
Would you please refer to them as well?<br>
<ol>
<li>For the former issue, it would be beneficial for my geometry if
results could be displayed in a cylindrical coordinate system. Is it
possible? At present I generate an alternative nodes and element file,
where the nodal coordinates are in r-<font face="Symbol">q</font>-z
rather than x-y-z (BTW, I have noticed that the elements cannot be
input on a separate file. Why?), but find it quite inconvenient and
wasteful.</li>
<li>Is there a way to scale differently the various coordinates? It
would be convenient for slender geometries in general, e.g, a high
length-to-diameter-ratio cylinder.<br>
</li>
<li>A tiny-but-irritating problem - whenever I start Gmsh GUI and
wish to open or merge files, it starts at a certain folder where Gmsh
executable resides, rather that the folder I start from (where the
post-
files and a link to the Gmsh executable reside). How do I customize it
to start browsing for these files from the current (or other) folder?</li>
</ol>
<font color="#ff0000"><i><b>PS:</b></i></font> I also attach the files
of the mesh in cylindrical coordinates
(post-1r.msh) and the associated options file (post-1r.msh.opt).<br>

<pre wrap="">Is it possible in Gmsh to display results along line of nodes and elements
as x-y graphs (e.g., the solid and fluid nodes and elements temperature
fields along an axial line)? At present I do it manually, by importing parts
of the output into Excel, which is rather cumbersome. The answer to this
question is therefore the most urgent.

<pre wrap="">The geometry of the steam generator we develop is rather inconvenient to
display, since it comprises of several concentric cylinders having narrow
gaps between each other, and also having bases. In order to display the
results, it would be convenient if parts of the model can be unselected, so
that only desirable parts temperatures contours, say, are displayed. The way
I do it now is by defining many views (around 100), each devoted to a
certain group of the nodes or element and a certain field values. Is there a
more elegant and simpler way to do it? Are the "Physical Names" properties
useful for this? There is very limited documentation of their use in the
post-processing part of Gmsh (provided I do not use Gmsh geometry and mesh
processors).

I think one way would be to set the "elementary entity" or "physical
entity" tag of the elements in question. You can select visibility by
either of these. These are two of the three or four integer tags that
each element gets in the $Elements block. Would it be possible to
modify your output routine to do that? I don't think you need to
worry about Physical Names, although it is nicer to refer to "wall"
than physical entity 2, e.g.
