    Hi everyone,
    these days I am visiting Urbana University - before coming to the
    conference in Chicago - trying to setup a cosmological simulation.

    I wrote some code to input particle positions/velocities/masses and it wor
    fine, mapping on the grid their density, and so on...

    Adding a new routine to setup the gas properties on the mesh, I am using
    particle density 'pden', as computed by 'MapParticlesToMesh'. I realized
    that, after calling 'ParticleToMesh', temp_buff2 has the right value of
    density, but solnVec doesn't change. I mean, copying temp_buff2 to
    solnVec, doesn't work, and the 'pden' subarray comes out with the same
    initial values.

    This could be either a coding bug - some non standard Fortran procedure -,
    or a compiler bug. I have no idea about what is going on.

    The machine I am using is a 24 processors SUN with:

            SunOS titania 5.8 Generic_108528-22 sun4u sparc SUNW,Sun-Fire
            f95: Forte Developer 7 Fortran 95 7.0 Patch 111714-06 2003/04/10

    The Makefile.h is attached.
    The FLASH version is 2.3

    Thanks,
    Claudio.
