#867: Add parameter to poison periodic boundaries -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Add a parameter to poison periodic boundaries before the periodicity condition is applied. This allows detecting errors in the periodicity boundary condition, which does not work if there are multiple local components per process.
