functions in bowtie.i - n

    nbow, map  
 or nbow, file  
 or nbow, rt, zt  
 or nbow, rt, zt, ireg  


prints information about topological oddities in a mesh.  
MAP is a bowtie map as returned by the bowtie function.  
FILE is a binary file containing rt, zt, and ireg arrays.  
RT, ZT and IREG are 2-D arrays defining a quadrilateral mesh.  
The information printed includes the zone index (corner with  
the largest indices) of zones which are concave (boomerangs)  
or bowtied, and of zones with negative area.  You can set  
the global variable nbow_negative to 1 to reverse the default  
sense of positive area.  By default, only the first 10 zones  
in each category are printed; use the all=1 keyword argument  
to print a complete (and maybe very long) list.
