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
