Dear all,

There are two questions about FreeFem++.

1. I would like to ask if FreeFem++ supports **distributed** three-dimensional structured or unstructured mesh used in parallel computation?  
we may involve in adaptation refinement.
2. For 3D parallel computation, What is the largest scale and the maximum number of grid cells of FreeFem++ simulation at present ?
