field data transfer

Hi,

I am actually working of field data transfer techniques when remeshing is needed during analysis of metal forming process.

some
researchers use a so called Linear interpolation technique using the
volume coordinates as shape functions to transfer a field from a mesh
to an other.

 Is there any one who used this technique in such a problem? 

If there is any, could he tell me which are the advantages of the technique and its disadvantage?

Is there any tests to validate the method?

 Many thanks in advance
