$deformboundary is a command to change the shape of mesh while does not remove any point.

type1 type2 f1 f2  f3 f4  f5 f6  f7 f8 f9 f10
type1=1 : rectangular
f1:xmin
f2:xmax
f3:ymin
f4:ymax

type2=1 :  (f5,f6) is the center point, (f7,f8) is the left new point,  (f9,f10) is the right new point. The program will push down the top point at (f5, f4) to (f5,f6), (f1,f4) to (f7,f8) , (f2,f4) to (f9,f10) .

type2=2 :  (f5,f6) is the center point, (f7,f8) is the left new point,  (f9,f10) is the right new point. The program will push up the bottom point at (f5, f3) to (f5,f6), (f1,f3) to (f7,f8) , (f2,f3) to (f9,f10) .

type2=3 :  (f5,f6) is the center point, (f7,f8) is the bottom new point,  (f9,f10) is the top new point. The program will pull left the right point at (f2, f6) to (f5,f6), (f2,f3) to (f7,f8) , (f2,f4) to (f9,f10) .

type2=4 :  (f5,f6) is the center point, (f7,f8) is the bottom new point,  (f9,f10) is the top new point. The program will push right the left point at (f2, f6) to (f5,f6), (f1,f3) to (f7,f8) , (f1,f4) to (f9,f10) .

   
type2=5 :  (f5,f6) is the final moving point, (f5, f7) initial point position. The mesh will be move down or down since it only moves the y-axis. 

type2=6 :  (f5,f6) is the final moving point, (f7, f6) initial point position. The mesh will be push left or right since it only moves the x-axis. 

type2=7 :  (f5,f6) is the final moving point, (f5, f7) initial point position. The mesh will be move down since it only moves the y-axis. There is region at thickness of dy (f8) will be moved together

type2=8 :  (f5,f6) is the final moving point, (f7, f6) initial point position. The mesh will be push left or right since it only moves the x-axis. There is region at thickness of dy (f8) will be moved together 

type2=9 :  cos kx funciton push down 

type2=10 : cos kx function pull up 

Type2 among 101 to 110 will be equal to type2 among 1 to 10. But we will try some method to make the transition of mesh size more smooth. 

type2=101 :  (f5,f6) is the center point, (f7,f8) is the left new point,  (f9,f10) is the right new point. The program will push down the top point at (f5, f4) to (f5,f6), (f1,f4) to (f7,f8) , (f2,f4) to (f9,f10) .

type2=102 :  (f5,f6) is the center point, (f7,f8) is the left new point,  (f9,f10) is the right new point. The program will push up the bottom point at (f5, f3) to (f5,f6), (f1,f3) to (f7,f8) , (f2,f3) to (f9,f10) .

type2=103 :  (f5,f6) is the center point, (f7,f8) is the bottom new point,  (f9,f10) is the top new point. The program will pull left the right point at (f2, f6) to (f5,f6), (f2,f3) to (f7,f8) , (f2,f4) to (f9,f10) .

type2=104 :  (f5,f6) is the center point, (f7,f8) is the bottom new point,  (f9,f10) is the top new point. The program will push right the left point at (f2, f6) to (f5,f6), (f1,f3) to (f7,f8) , (f1,f4) to (f9,f10) .

   
type2=105 :  (f5,f6) is the final moving point, (f5, f7) initial point position. The mesh will be move down or down since it only moves the y-axis. 

type2=106 :  (f5,f6) is the final moving point, (f7, f6) initial point position. The mesh will be push left or right since it only moves the x-axis. 

type2=107 :  (f5,f6) is the final moving point, (f5, f7) initial point position. The mesh will be move down since it only moves the y-axis. There is region at thickness of dy (f8) will be moved together

type2=108 :  (f5,f6) is the final moving point, (f7, f6) initial point position. The mesh will be push left or right since it only moves the x-axis. There is region at thickness of dy (f8) will be moved together 

type2=109 :  cos kx funciton push down 

type2=110 : cos kx function pull up
