Er… Seems that definition of `plasticStrainStepCompiled` is missing? |
Just want to mention that I've made a first trial on RBF-FD recently: https://mathematica.stackexchange.com/a/309006/1871 |
The i.c. is not ignored. It's because `NDSolve` hasn't used enough grid points for spatial discretization. Hans doesn't observe this phenomenon in version 7 because there's a silent change in prior error estimation of `NDSolve` in version 9. This... |
I'm not sure when it's improved, but at least since _v12.3.1_, we no longer needs to split into triangle!: area[pts_] := Area[Polygon[pts], Assumptions -> {0 0} (* {28} *) |
Cross posted [in Mma.SE](https://mathematica.stackexchange.com/q/268522/1871). Solved there. |
Thank you for your reply. |

For second error: I want to save the result of NDSolve[] to slider. I think when the first error is solved. The second error will be solved automatically. |
This is unusual. It appears to be a quick rewrite of ["Standard Packages for Mathematica 3":][1] which has the same first sentence "The Durbin-Watson d statistic is used for testing the existence of a first-order autoregressive process" on page... |
