Please keep the list in CC, and avoid top-posting [1], this list favours bottom 
posting [3] or interleaved style [2] to make the archives more readable.

The 'msh' package on SourceForge [4] has an interface to gmsh [5] for creating 
triangular and tetrahedral unstructured meshes.
If you have FeniCS [6] installed before you install msh, it also provides 
refinenement.
An example of a moving front is given for example in the demo for 
msh2m_displacement_smoothing:
