How do I run Cactus until a given coordinate time instead of to a given iteration number?
Instead of setting cactus::cctk_itlast set cactus::cctk_final_time to the required coordinate time, and also set cactus::terminate = “time”. • Output to screen using the Info IO method of IOBasic doesn’t work. I want to watch min/max values for ‘wavetoy::phi’ during a cactus run on stdout. For that, I added IOBasic::outInfo_every = 10 IOBasic::outInfo_vars = “wavetoy::phi” to my parameter file. Thorn IOBasic is active, but I only get the iteration number and coordinate time printed to screen. You need to activate a thorn which implements the min/max reductions, for example CactusPUGH/PUGHReduce. • I get an error saying “CCTK_Equals: First string null”. The routine CCTK_Equals tries to look at the value of a keyword or a string parameter. The value “null” indicates that this parameter has never been set. The problem could be that Cactus mis-detected the way the Fortran compiler does its name mangling. The linker then creates two tables that contain parameter values, where one is set by
