I am trying to mesh a model and I keep on running into problems.[IMG]file:///C:/Users/Milad/AppData/Local/Temp/moz-screenshot-1.png[/IMG] The model is of a house, there is a roof cavity which is in contact with a 10mm thick ceiling, and then a room (in 2-D). I have attached some pdf's of the model. My problem comes when I try to mesh, I keep on getting the following error:
The volume mesher is unable to build an element from the current face, and cannot continue.
1) Check the quality of the surface mesh in this vicinity,
This can be achieved by viewing the Mesh before Inflation or the Inflated Front.
2) Check that the mesh spacing is less than the distance
between neighbouring CAD faces.
3) If inflation is being used, try increasing the Minimum
Internal Angle. With extended inflation layers and curved surfaces an angle of > 15 degrees may be appropriate.
4) Try reducing the mesh spacing in this area by adding
appropriate mesh controls and remeshing.
F3 coordinates[ 6.1312E+02, -1.8583E+02, 1.0000E+00]
[ 6.1241E+02, -1.9078E+02, 0.0000E+00]
[ 6.2219E+02, -1.8587E+02, 1.0000E+00]
Current mesh spacing = 1.0000D+01
I have tried several different meshing techniques and they all produce errors. I have tried to use virtual topology but it keeps on saying 'failed to merge the specified topological entities'. Any help or information will be very much appreciated, thanks.

fyi, to attach pictures you are going to have to either upload them to a website or attach them to the post (see Manage Attachments at bottom)
the way you are doing it is linking to pictures on your hdd, which we cant access!

I can see the images in your attached pdfs, but I can't diagnose the problem from here... Is this a model you could share with the group? Perhaps someone could take a look at it and get back to you?
