The 3D-DDCC mainly uses cgs unit (not all parameters). But the gmsh file may not created by cgs unit. $ifzscaled ($ifxscaled, $ifyscaled) is a scaling command to rescale the gmsh's dimension. For example, if people create a gmsh file and it's z-dimension is using nm as the unit. He can use $ifzscaled to convert the file into cm unit.

for example:
 1nm=1.0e-7cm

Therefore, if the mesh file use nm, then we need this command

 $ifzscaled
 1.0e-7   

If all directions using nm, then
 
 $ifxscaled
 1.0e-7  
 $ifyscaled
 1.0e-7  
 $ifzscaled
 1.0e-7  

If the x and y direction use um and the z direction uses nm, then

 $ifxscaled
 1.0e-4  
 $ifyscaled
 1.0e-4  
 $ifzscaled
 1.0e-7
