#449: Check for periodicity of initial data with Periodic thorn --------------------------+------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Other | Version: Resolution: | Keywords: Periodic --------------------------+-------------------------------------------------
Comment (by eschnett):
All thorns are supposed to fill in all grid points. If necessary, the thorns have to synchronise and apply a boundary condition.
A generic mechanism for testing this would be to have an independent thorn that takes a grid function where supposedly all grid points are valid, makes a copy, applies a symmetry boundary condition to the original, and then compares to the copy. Any difference is an error. This would also test synchronisation and boundary conditions.
