@e-carlin the change to the openmc app was to allow the weight-windows output file to be saved after running a variance reduction sim. There is also an option to save the weight-windows file to the user's lib directory and use that file when running a new simulation. It does this by saving the weight-windows file as a sim_file after the simulation completes (which I think brings it back from the remote (sbatch) to the local server). That sim_file is then available to copy into the lib dir if the user requests it. I tested on dev with a local sbatch and it seems to work ok.

To test it, use the Tokamak Reactor example, then set the Variance Reduction parameters on the Visualization page:

Then run the sim, and the weight windows download link and button will appear on the simulation status:

When you select the "Apply Weight Windows" it will show a confirmation page, and then copy the sim file to the lib and set up the simulation for running with that lib file.

Works well. Left two comments about the structure.
