*	Two part update of the restricted full norm dissipation operators. The first	diener	2006-03-10
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	part is an optimisation. Previously the coefficients were constructed every time the dissipation was applied. This turned out to have a significant overhead, especially for large domains. Now the coefficients are constructed only once for each patch on each processor and stored. The thorn now uses the aliased functions MultiPatch_GetMap and MultiPatch_GetMaps (provided by thorn MultiPatch) to figure out how many patches are present and which patch is currently being worked on. These dissipation operators will not work unless the MultiPatch thorn is used. Right now this should not be a problem (but can be changed if it is), unless somebody uses dissipation operators outside of the multipatch infrastructure. The second part is an update aimed at making the restricted full norm dissipation operators better behaved on grids with very different number of grid points in different directions. For that reason the parameter: diss_fraction has been made vector valued (of length 3), so that the width of the transition region from the boundary to the interior operators can be controlled separately in the 3 dimensions. Unfortunately this means that any parameter files, that explicitly sets this parameter, will have to be modified. I don't think too many people are using the restricted full dissipation operators yet, so it shouldn't cause too many problems. In additiona new parameter: h_scaling has been introduced. This parameter is also vector valued of length 3 and allows the local grid spacing to be rescaled to more closely resemble the physical grid spacing in any dimension. Note, these changes only affect the non-diagonal dissipation operators. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/SummationByParts/trunk@61 f69c4107-0314-4c4f-9ad4-17e986b73f4a

Since the dissipation operator in the interior uses a stencil that is one point wider than the derivative operator, an additional check on the number of ghostzones in multi processor runs have been added.

	finite difference operators. Not fully tested yet. The MoL dissipation interface was shamelessly stolen from Eriks Dissipation thorn (in AEIThorns). Things to do: Add a test for the presence of MoLQueryEvolvedRHS (since the use of dissipation is optional, I didn't want to require the presence of this routine). Add compatible dissipation operators to the other finite difference operators. More testing. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/SummationByParts/trunk@21 f69c4107-0314-4c4f-9ad4-17e986b73f4a
