This HTML embeds an exported model. Click Fetch cross sections
to pull the nuclide data this model needs from
yamc-data.xsplot.com into browser tab memory (nothing is saved to
disk), then Simulate to run.
Surfaces (editable, CSG only)
Heads up: changing surface parameters can produce broken
geometry -- surfaces overlapping in ways the engineer didn't
intend, cells with no inside, particles that get stuck on the
boundary. The simulation may then crash, give garbage results, or
hang. Mesh-based geometries are not editable from here. Make small
changes and re-run.
