    Hello, X-flow,

    When I tried to decompose examples/testlid/testlid.msh into two parts, the output looks NOT correct . Do you get the same problem ?

    If you use latest version from svn which is 1.4, you should use gmsh 2.5.
    If you are using v 1.3, you should use gmsh > 2.0 and < 2.5.

    Hi, X-flow,

    I use the latest version which is 1.4 and try gmsh version 2.5 and 2.4. both get the same error.

    It is a bug then. Can you try and correct it?

    Yes, I'm trying to do it. it looks the problem comes from additional wrong old patches.

    I tested with latest version from svn and latest gmsh and did not get that error.
    Can you tell me exactly what you are doing? What steps?

    Hi, x-flow,

    Thank you for your reply.

    1) svn co https://openfvm.svn.sourceforge.net/svnroot/openfvm openfvm

    2)cd /openfvm/trunk/OpenFVM/Flow/parallel

    3) modify makefile ,then make

    4)then , cd /examples/testlid, gmsh testlid.geo -3

    5)  ../OpenFVM testlid d 2

    6) gmsh testlid.000.msh testlid.001.msh

    You can't load 2 files simultaneously. If you want to see whole mesh with partitions load testlid.ppp.msh
