openmc-voxel-to-vtk loads entire file in memory
Created by: paulromano
An ANL user reported running out of memory when trying to convert a 1000x1000x1000 voxel plot to VTK. While OpenMC writes the voxel file one slice at a time, the
openmc-voxel-to-vtk script reads all data in before trying to convert it to VTK. It seems like it should be pretty straightforward to have
openmc-voxel-to-vtk also convert one slice at a time to not consume so much memory.
@pshriwise Do you want to look into this when you get a chance? (on top of the million other tasks you have going on :)
