Does WENOEXT work on 1d advection test case?

[wangsen992]

Hi there,

I am trying to test the package by trying it on a 1D test case running with scalarTransportFoam. When using the package directly by replacing the divScheme for div(phi, T) to "Gauss WENOUpwindFit 4 0", or with any other order number, the result is extremely diffusively, behaving like a basic upwind scheme.

After checking the constant/WENOBase* folder, particularly the file "StencilIDs", I realize that for most elements in the file, it is empty,

whereas for your tutorials, it looks like this.

Therefore, I am wondering if there is some limit/check in the implementation that prevents the scheme from working on 1D cases, therefore it simply behaves as an upwind scheme (as in no explicit correction is applied)?

Thank you very much and looking forward to hearing your replies!

Best wishes,
Sen
