... are relevant for all LRN models. The modified model gives asymptotically, in the sense of mesh refinement, identical results to the baseline model. For coarser meshes y + ⩽ 10 , the present method improves numerical stability with less mesh-dependency than the non-modified model. Results are included for fully...
