Hi, 
 	  
   	For a magnetostatic application in 2D I would like to know the length of an isoline in a specified region. 
 	Does anyone know if this is possible to obtain within Flux? 
 	I am able to do it with external image processing but if I could automate the process within Flux it would be of great help.  
   	  
   	Thanks, 
 	Ben
