<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>Dear
Authors,</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=443234012-23062005></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>First of all I have
to congratulate for your mesh generator. It is an excellent tool, and
I appreciete using it.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>I also have a
question to you. I intend to test the difference between the groundwater flow
regimes of a pure discrete network model and a combined discrete-continuum
model.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>For the latter
purpose I need a mesh generation approach which can combine 2d and 3d elements
in a manner that the nodes and edges of neighbouring elements of different
dimensions are geometrically identical.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>In other words I
need to fill in the space with tetrahedrons among the 2d element sheets
representing fractures of varying direction.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>I tried to merge a
pre-generated discrete finite element network into a geometric volume in GMSh,
and lounched a 3d mesh generation, but the sides of the 3d elements doesn't seem
to fit the edges of the 2d elements along fracture plains.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>Do you have a method
for solving this problem?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=443234012-23062005></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=443234012-23062005>Thanks and best
regards:</SPAN></FONT></DIV>
