* Implement RK45 Cash-Karp integrator in MoL.schnetter2006-02-19
| | | | | | | | | | This integrator is similar to the existing RK45 integrator. It also supports adaptive time stepping, but uses slightly different coefficients. The Numerical Recipes say that it has "slightly better error properties". git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@110 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b

* Peter Diener's RK65 and RK87 adaptive timestep integrators.hawke2006-01-23
| | | | | | | | | As yet not altered to do grid arrays. As with RK45, adaptive timestepping does not work with mesh refinement. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@106 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b
* Remember the variable index of the scratch variables.schnetter2005-12-11
| | | | | | | | | | This saves calling CCTK_FirstVarIndex during each MoL iteration. This function is expensive, as it performs case insensitive string comparisons, and it showed up high on a profile of some of the Mexico tests, which integrate small domains over long times. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@105 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b
* Add const and restrict qualifiers to the pointers.schnetter2005-12-11
| | | | | | | | | | Simplify some complex arithmetic. Initialise the error variable in the RK45 integrator only after the last iteration. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@104 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b
* Handle CCTK_SCALAR in the same way as CCTK_ARRAY. Previously,schnetter2005-12-11
| | | | | | | | | | CCTK_SCALAR variables were rejected. This is most likely just an oversight, since no one so far wanted to integrate CCTK_SCALAR variables. The change is trivial. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@103 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b

* Correct critical error in the RK45 time integrator.schnetter2005-12-11
| | | | | | | | The current time and the time step sizes were not set correctly. That led to first order convergence instead of fifth order convergence. git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/MoL/trunk@101 578cdeb0-5ea1-4b81-8215-5a3b8777ee0b
