* Add Jacobian gridfunctions to GenericFDIan Hinder2012-03-21
| | | Storage is disabled by default. These are here so that benchmarks and tests can be run using multipatch thorns without having to have another thorn to provide the Jacobians. We should probably have a function to initialize them as well.
* GenericFD_AssertGroupStorage: Use const for input argumentsErik Schnetter2012-02-20

* MathematicaCompat.h: Restore macrosIan Hinder2012-02-11
| | | These were removed in c9ec36148e7d255006d732fb16c00c6a64cfa4c9, but this causes existing thorns to fail to compile. We keep them here for compatibility.

| * Remove support for pown functionErik Schnetter2011-12-29
| | | | | | | | pown is only supported in OpenCL, and does not seem to give a performance improvement.
| * Generate pown(), which exists in OpenCLErik Schnetter2011-12-19
| | | | | | | | Also provide pown() if not generating OpenCL code.
| * Replace almost all functions Sin[x] etc. with their C names sin(x) etc.Erik Schnetter2011-11-29
| | | | | | | | | | | | Replace almost all functions Sin[x] etc. with their C names sin(x) etc. already in Kranc instead of via the C preprocessor, because this allows more optimizations in Kranc. Implement some of these optimizations.

* | GenericFD: Add GenericFD_EnsureStencilFitsIan Hinder2011-05-27
| | | | | | | | This function checks that there are enough ghost and boundary points for the stencil widths (ni, nj, nk) passed to it.
* | GenericFD.c: Add GenericFD_GetBoundaryWidthsIan Hinder2011-05-27
| | | | | | | | Based on the existing GetBoundaryWidth but returning all the widths. GetBoundaryWidth now calls the new function.

* | Tidy up grid indexing using CCTK_LSSH macroErik Schnetter2011-05-27
| | | | | | | | | | | | | | Clean up the code that uses lssh. Note: Although most people don't know about lssh, it's defined by the flesh, and e.g. all standard Cactus boundary conditions use it. However, Carpet currently always sets lssh to lsh, so the difference is "hidden".
* | Make IfThen available in FortranErik Schnetter2011-05-27
| |
* | Make multiplication by Jacobian selectable at run-timeIan Hinder2011-05-25
| | | | | | | | Use of the Jacobian is determined by the user setting the jacobian_group parameter. Also provide a parameter jacobian_identity_map which the user can set to a Carpet map which does not require the Jacobian, in which case the Jacobian will not be applied.

| | | | | | | | | | | | | | | | | | | | | | | | Use "k" prefix more consistently in arithmetic macros. Improve vector code generation patterns. Move all vectorisation run-time out of Kranc and into a new thorn LSUThorns/Vectors, so that non-Kranc thorns can also use it.

* Use signbit insted of sgn in C.Erik Schnetter2010-02-13
| | | | | | Use constants M_E and M_PI instead of explicit constants in C. Append "d0" to constants for e and pi in Fortran to make them double precision.
