Hello all,
I'm an undergraduate working on a project to simulation a mantle convection model and this is the first time I've worked with a simulation code.  I've gone through a number of examples on the project site as well as the wiki but I still have a few questions.  I'm hoping this list can help me out .
1.  Does anyone have any recommendations for a cheap, easy to use mesh generation tool?  Recently I've found gmsh which looks promising.
2. I want to model three different bodies, each with different material properties.  How are material properties specied?  I have a feeling that material properties should specified in the code, but as of yet I've not seen an example of this.
Any help would be very welcome.  Thanks in advance!
