[[$deformboundary]] is the definition of N deform reions

 $deformperiod
 type  N_period  spacing
 type  N_period  spacing
 type  N_period  spacing
 type  N_period  spacing
 type  N_period  spacing

 type =1 (equal to $deformboundary type 1. No periodicity
 type =11 periodicity of deform region along the x direction. 
 type =21 periodicity of deform region along the y direction.

Example:

 $deformperiod
 1   1   0.0
 11  20  1.0
 21  2   2.0
