community,</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>I am trying to
use the background mesh feature of gmsh for adaptive meshing of my physical
problem. I am having difficulties with this feature probably because of
misuse. Here's what I do:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>1. I read the
geometry file.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>2. I merge the
previously made mesh file.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>3. I merge the data
containing the target mesh sizes (NodeData based although I tried ElementData as
well)</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>4. Mark the view
containing the data as background mesh.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>5. Mesh the geometry
through the menu.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=517121116-03032010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>Gmsh then fails
generating all kinds of errors. I have attached the files I have
used.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=517121116-03032010>If I look at the
manual and the example given, it seems to use a pos file as background mesh. I
however thought that the preferred way for large datafile transfer to gmsh was
to use the procedure indicated above (at least for
postprocessing).</SPAN></FONT></DIV>
