An Example Problem
Previous  Top  Next

Let us build as an example a circular inclusion between two plates. We will simply treat the plates as the top and bottom surfaces of a square enclosure, with the circle centered between them. Using the statements above and adding the required control labels, we get:
 
BOUNDARIES  
REGION 1 'box'   { the bounding box }  
START(-1,-1)  
LINE TO(1,-1)  
TO (1,1)  
TO (-1,1)  
TO CLOSE  
REGION 2 'blob'   { the embedded circular 'blob' }  
START 'ring' (1/2,0)  
ARC(CENTER=0,0) ANGLE=360 TO CLOSE  


The resulting figure displayed by the "domain" button is this:
