* MoL Updateeschnett2013-01-22
| | | | | | | | | | | | | | | | | | New integrator Euler. This is an explicit, first-order method, mostly useful for debugging. New integrators AB (Adams-Bashforth) with various orders. These are explicit integrators using several past timelevels to provide higher-order integration with a single RHS evaluation each. Introduce LinearCombination, a generic routine to calculate linear combinations of grid functions. This simplifies existing code, and can be overloaded if MoL should run on a device (e.g. with OpenCL). Replace cctk_lsh with cctk_ash where necessary. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@190 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b

* Comment or ifdef out complex variable support as Carpet doesn't like it.hawke2003-05-24
| | | | | | | To use the complex variable stuff right now you need to uncomment the appropriate groups in the interface.ccl and #def MOLDOESCOMPLEX in the appropriate files. It still probably won't work. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@13 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b
* Add support for evolving complex GFs and (real and complex) GAs.hawke2003-05-21
| | | | | | | | | Only works with ICN or RK2 for now - in fact this commit may break the generic RK methods temporarily. Note the documentation isn't quite right - there's no longer a seperate function for each different type... git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@12 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
