3 years ago For clarity, here is an overview of the key changes in this pull request:
- Changed the interpolation from the second grid to the base grid, allowing arbitrary second grids (including lower resolution)
- Moved the stencil creation to a single generic subroutine that can be used to create each stencil
- Added a small perturbation to the pressure solver to prevent singular values when using uniform base grids
- Moved grid creation and second derivative coefficients to generic subroutines in a GridModule
- New functions in the Python and Julia modules to produce Xdmf XML file, in particular for the uniform grids that allow for fast volume rendering
- A start to the documentation on ParaView visualisation, spatial derivatives and Hermite interpolation
Since the previous CreateMgrdStencil involved a lot of repeated code, I have moved the subroutine to generate this to a module, making the source more readable and the code cleaner.
