There is an error in LAMMPSPipeline.

When using the example of LAMMPSPipeline, this process cannot continue in "Insert Atoms". Dream3D will exit directly.

The Insert Atoms filter will insert a lattice of atoms for each grain using real life units. You would need a single nanometer sized grain (a single grain) to probably not have your computer run out of memory.
