I think a temporary fix could be to generate_coarse_mesh in the triangulation load checkpoint load data
And then for each step you want to load, to clear generate_coarse_mesh load checkpoint load data Which when thinking about it looks a bit absurd. If you have a small example i'd be happy to look at it! On Wednesday, February 19, 2025 at 1:02:26 p.m. UTC-5 jere...@gmail.com wrote: > triangulation.clear() removes all data.
