#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.

Please review this, this is necessary for refluxing tests.

looks harmless to me.

Looks fine to me too. Could you please also add a brief description to the documentation?
