#1058: Add "lapsefactor" parameter to EinsteinExact -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- I suggest introducing a "lapsefactor" parameter to EinsteinExact. This defines a transformation for the time coordinate between the underlying metric and the metric as will be used by Cactus. For example, setting lapsefactor=1/2 will lead to alpha=0.5 for the Minkowski metric, with the other metric components unchanged.
This complements the "shiftadd" parameters, and is very useful for testing.
