A 3D example of managing application data.The workflow is documented more extensively in A demonstration of how to manage application data. The image below is generated from the command
mpirun -np 7 example/userdata/p8est_userdata rotcubes 5 -I
and visualized with Paraview, combining a value threshold of 0.1 and up with an output of level 3 cells colored by MPI rank.
The 3D version of th this demo compiles from the same code as the 2D example userdata/userdata_run2.c with minimal redefinitions. In this sense, the code is mostly dimension independent.
