Determine max eigenvalue over Jacobian in a given point with solution values (states) Q.

All parameters are in.

Returns: Max eigenvalue. Result has to be positive, so we are actually speaking about the maximum absolute eigenvalue.

To obtain the best performance, I recommend to man inline command to this signature and to copy the implementation into the header.

So it would read

static inline double maxEigenvalue( ... ) { code here }

The GPU offloading requires static functions. As we cannot overload the original (virtual) function with a static alternative, we do the TBB trick and overload by adding an additional enum. It has no semantics but helps the compiler to distinguish the different function variants.

		double	t )

override

Refinement criterion.

Single black hole, low refinement (CCZ4ReSwi==2)

Single black hole (CCZ4ReSwi==6)

Single black hole setup with two refinement levels such that the finest volume is the same size as it is in the regular grid tests. We use two level of refinement which arrange around the area of interest. Within the innermost radius of 3.5, we enforce a mesh size of 0.04, while we have a compute cell size of at least 0.15 within the radius of 5. For everything futher away than 5 from the centre, we stick to the maximum mesh size.

We use the setup with

    python3 ccz4.py -impl fd4-rk1-adaptive -s two-punctures -maxh 0.4 -minh 0.04 -ps 6 -plt 0.5 -et 0.5 -exn test --domain_r 9.0 --ReSwi 7 -cfl 0.1 -outdir ./ --KOSigma 8.0

in standard benchmarks.

Alternative settings would have been

   double Radius[NumberOfRefinementLayers] = {5.0, 3.0};
   double MaxH[NumberOfRefinementLayers]   = {0.3, 0.15};

Parameters

Q	This is the (current) solution. The data is not set to a valid value throughout grid construction. That is: If t equals 0.0, you cannot assume that Q is properly initialised. Therefore, Q usually is only evaluated by dynamic AMR codes which make the solution follow
