Dear forum, I am using Paraview to visualise a large dataset coming from a direct simulation of turbulence (size of the original data of order 10-100GB). Naturally, I am running in parallel on a cluster (using the mesa), which also works very well.
However, there is one issue: I want to visualise isosurfaces of a quantity, and colour them using another scalar quantity. When running serial, everything is fine. When using multiple processors with MPI leading to the data being distributed, the rendering of the isosurfaces is still ok. However, the colouring seems to be based on the scalar field of the first data segment (i.e. the first processor) only. This then leads to very visible boundaries between the processors as the colours are clearly not correct (see example on http://www.mech.kth.se/~pschlatt/files/resampled.jpg). Again, running on a single processor everything is correct, and running on different numbers of processors will shift the edges. This issue could be confirmed in all version up to 3.10. Due to this, I am required to run in serial, which is very painful both due to memory requirements and very long rendering times (up to 15 minutes for a single frame). Thus, if there would be a simple fix, I'd be very interested. Thanks a lot in advance for any hint.
