Netgen in parallel using MPI

    Hi there,
    I just succesfuly compiled Netgen-5.1 with MPI support. And now I don't know how to enable the meshing process run in parallel
    When I run "mpirun -np 4 netgen" it works, it starts 4 processes but if I generate the mesh then just one of all the 4 processes runs on 100% a the other ones are doing nothing.
    Is there someone who can give me the suggestion how it should be done to enable the real parallel meshing?

    Thank you so much in advance.

    Netgen is not thread safe, it contains nasty global variables (for settings, and possibly more), I'd strongly advise you to not use it more than once at a time.
