questions:</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=576510109-10072008>1. I am wondering
about the order in which various sections appear in the output file. The
documentation seems to imply that PhysicalNames follows the Elements section,
however this is the other way round when looking at output files. Is the order
then always: </SPAN></FONT><FONT face=Arial size=2><SPAN
class=576510109-10072008>MeshFormat, Nodes, PhysicalNames, Elements, etc. or is
it free (which makes reading the file a bit more hassle).</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=576510109-10072008>2. I experimented a
bit with generating multiple physical tags and saw that in this case
multiple entries of the specific elements are generated in the output file (not
what I would like). I was also a bit puzzled by the order in which these
duplicates (with different tag) appear. In the case of 2 tags, the entries were
listed reversed wrt their definition in the geo file. If the range of tags that
you use is similar then there is no way to distinguish between different
physical properties (e.g. tag1 = material type, tag2=source strength, etc.). I
guess I need to use a specific range of tags to identify what they mean. What
puzzles me is why the file format allows for 'number-of-tags' if this can not be
influenced? Is there perhaps another way to force multiple tags on a single
output line?</SPAN></FONT></DIV>
