I have no time to look further to this today. A reason could be that your 
background mesh is not fine enough, so try to use more vertices. Try also to 
visualise Omesh and check which are the references you obtain. Tell me if you 
still do not understand I will try to answer as soon as possible.

Both of them are possible I think. FEM part is still completly undocumented 
and I did not anounce it since some functionalities are still missing. I will 
try to send exemples one this mailing list and update the documentation on 
this particular case this week-end.
