Hello all,

I am a new deal.ii user pursuing a PhD in thermal management of printed 
circuit boards .I am trying to analyse a steady state heat transfer problem 
on  a 3d rectangular domain. The domain has a convective heat flux boundary 
condition on the top and bottom surfaces. There is also a discrete heat 
source on the top surface.

I am inputting my geometry using as a vtk file using the *read_vtk()* 
function. My questions:

-          Is there a way to include the boundary conditions in the input 
file?

-          Is it possible to include the material properties of the cells 
in the input file. Each cell can potentially be anisotropic  and have 
different thermal conductivity in the x, y and z directions. 

>From reading the documentation it seems that the vtk input file can include 
MaterialID and BoundaryID data, but it would be useful for me to also 
include the accompanying properties of the identified materials and 
boundaries.

I appreciate your assistance in advance, especially an example 
implementation of such a file.

Kind regards,
