* Runge-Kutta (Fehlberg) 45 with error estimation.hawke2004-09-06
| | | | | | | | | | | | | Fourth order accurate evolution with an additional fifth order step for error estimation. How much sense the error makes is unclear to me, but hey. For the moment the error is stored in an internal MoL array ErrorEstimate; there is one per evolved variable. At a later point this may be moved out to user thorns who can register their own etc. As the implementation uses 6 evaluations of the RHS (necessary) and 6 levels of scratch space (one more than necessary - laziness kicked in) then this is very expensive. This is a partial fix for PR/1840. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@74 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b

* The Method of Lines thorn (version 2 - see below).hawke2003-04-23
MoL provides generic integration methods for multiple thorns simultaneously. By providing a layer between the driver and evolution thorns, this should mean that some technical issues to do with mesh refinement can be ignored. It also allows you to choose different evolution methods (in time, at least). But the primary purpose is to unambiguously evolve models in different thorns at the same time. This is version 2 - the one that will work with mesh refinement. It's a straight copy of HawkeCVS/Public/CactusMoL2/MoL2 and I haven't checked that it will work "as is" with the new name (one of the reasons it goes into Alpha). At the moment the only evolution method guaranteed to work with mesh refinement is ICN, although RK2 should. The generic RK methods will do something that will be subtly wrong... Note that the "old" way of registering variables (through the functions declared in header files) is still there. As soon as function aliasing settles down, this will be removed. Also to be done: Better documentation Tidy up the code (especially the debugging statements) Optimize Add various useful time evolution methods. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@2 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b
