o parameter Shap_noSlip replace CPP option NO_SLIP_SHAP
o working arrays (in common block SHAP_FILT.h) become argument
  of Shap_filt S/R.  => Enable to filter 2D fields.

6 #include "CPP_OPTIONS.h"

8 C Use [1-d_yy^n)(1-d_xx^n] instead of [1-d_xx^n-d_yy^n]
9 C This changes the spectral response function dramatically.
10 C You need to do some analysis before changing this option. ;^)
11 #define SEQUENTIAL_2D_SHAP
12
13 C This invokes the older code which produces the same numbers
14 C and might even be faster because it does not do multiple
15 C exchanges within the filter. However, this requires the
16 C overlap to be sufficiently wide and also does not work
17 C for arbitrarily arranged tiles (ie. as in cubed-sphere).
18 C *DO NOT USE THIS OPTION UNLESS YOU REALLY WANT TO* :-(
19 #undef USE_OLD_SHAPIRO_FILTERS
20
21 #ifdef USE_OLD_SHAPIRO_FILTERS
22 C Boundary conditions for U,V Shapiro code
23 C Horizontal shear is calculated as if the boundaries are no-slip
24 C Note: option NO_SLIP_SHAP only used in OLD_SHAPIRO_FILTERS ;
25 C it is replaced by parameter "Shap_noSlip=1." in new S/R.
26 #undef NO_SLIP_SHAP
27 #endif
