<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>I have become a fond user of gmsh when creating
geometries for thermal calculations. I’ve run in to trouble in these
calculations when the temperature gradient is very steep with a mesh that is to
coarse. The problem is that I do not need a fine mesh anywhere else but close
to the certain boundaries where the temperature gradient is steep. Creating a
fine mesh in the whole volume demands to much computational time. Is there a
way to separately specify the grid size within different physical groups?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

to be generated? I would like to be able to produce only prisms or hexahedrons.
I’m using Gmsh as a mesh generator for SAFIR (a thermal and mechanical FEM-solver
for fire exposed structures developed at <st1:place w:st="on"><st1:PlaceType
w:st="on">University</st1:PlaceType> of <st1:PlaceName w:st="on">Liege</st1:PlaceName></st1:place>)
and it can only understand prisms and hexahedrons in the 3-D case.<o:p></o:p></span></font></p>
