WENO Test
- Roland tried multiple different resolutions (up to 8 times more and 16 times the time resolution, as well as 2 times bigger and offset from 0 grids) none of which prevented NaNs to from on my laptop
- next thing to try is to find out which is the exact optimization options that causes the NaN
