[Gmsh] Adaptive meshing with background mesh

[Martin Vymazal]

Hello,

I made a mistake while creating the ParabolicProfile.pos attached to  
my previous post. I defined the parabolic function and then I applied  
the 'warp' plugin, which was not a good idea. Warping results in a 3D  
surface with nonzero z-coordinates and meshing a plane disc with this  
surface as background mesh generates the error messages about 'No  
element found containing point ...'

Unfortunately, gmsh still ignores the characteristic lengths set in  
the *.pos file and meshes the circle with uniform mesh. Does anyone  
have the same problem as me? I'm stuck since I'd like to make some  
locally adapted 3D meshes and this feature seems to be broken even in  
2D.

Best regards,

    Martin Vymazal
