Synopsis
        sfescfgrid2 < spdom.rsf > out.rsf vspl=vspline.rsf na=360 mdist=SF_HUGE thresh=1e-6 morder=ESC2_MORDER niter=nx atraced=n mtraced=n cmix=n tracebc=y verb=n

 
Parameters
       
 
bool atraced=n [y/n]
true - output map of all traced points
 
bool cmix=n [y/n]
true - check for color mixing
 
float mdist=SF_HUGE
Maximum distance between points in F-D stencil
 
int morder=ESC2_MORDER
Maximum order in F-D stencil
 
bool mtraced=n [y/n]
true - output map of points traced because of mdist criterion
 
int na=360
Number of phase angles
 
int niter=nx
Maximum number of Gauss-Seidel iterations
 
float thresh=1e-6
Convergence threshold
 
bool tracebc=y [y/n]
n - do not trace B.C. points
 
bool verb=n [y/n]
verbosity flag
