    I noticed that my (2D) code crashed with a Segmentation Fault when the domain size became to big.
    I fixed it by changing the following in superVtmWriterXD.hh

    change this:

    Code:
    float bufferFloat[fullSize];

    to this:

    Code:
    float* bufferFloat = new float[fullSize];

    to allow bigger domain sizes for a limited number of cpu’s with MPI.

    I would be happy to hear if I fixed this well.

    Thanks

    Thanks for the report.

    I have fixed this in our master branch through

    Code:
    std::unique_ptr<float[]> bufferFloat(new float[fullSize]);

    which handles deleting the allocated memory as well. The same approach was already implemented in the 3D case.

    Ok, great! Thanks for the update with the improved fix.
