<P><FONT SIZE=2 FACE="Arial">Hi,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I have problems meshing a 3D STEP geometry (see attachment). I cannot generate a mesh which is continuous at the interfaces so that no heat can flow between the 3 bodies contained in the model. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">I have tried to "heal" the geometry using netgen, and import the result into gmsh to generate the mesh, but it was still noncontinuous.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">In the message window I have seen that gmsh (2.5.1) also performs some "healing" (but surfaces are not sewed as in netgen), but this apparently does not help here. When I generate the mesh in netgen, I get a continuous mesh, but I would prefer to generate the mesh with gmsh. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">This is a simplified test geometry - for a more complicated geometry, I get a crash in netgen, and gmsh complains about overlapping faces.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Any idea how I can generate a continuous mesh in this case?</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Thank you,</FONT>
