    Hi all, I noticed that even with the same parameters my unstructured mesh seems to be changing slightly each time it's generated. Could you shed more light on whether there is randomness in the generation of faceted and octree meshes, and if there is, how to fix the random seed to ensure reproducibility, please?

      Hi @NaraSakamoto

      how are you generating unstructured meshes? Using the octree mesher? Via the UI or the Python script?

      I guess the parallel operations may execute differently in each run. One operation to a node or tet could influence downstream operations on adjacent nodes/tetra. The ordering will make a difference.

        Hi @bryn, I'm meshing an implanted device as a faceted mesh which is then embedded in an octree mesh. This is all through the Python API.
