@spinicist Yes, if you could please check out the patch and just verify that it works locally for you, that would be helpful.

Yes, the need to call `OverrideBoundaryCondition` is not intuitive. As @dzenanz mentioned, it would be nice to have this noted in the [_Iterators_ chapter of the Software Guide](https://itk.org/ITKSoftwareGuide/html/Book1/ITKSoftwareGuide-Book1ch6.html#x44-1150006.4). We [recently made it easier to contribute to the Software Guide on GitHub](https://discourse.itk.org/t/contribute-to-the-itk-software-guide-on-github/695/2).
