* ``i1`` is the number of cells of PML to use on all sides of the model domain, or ``i1`` is the number of cells of PML to use on the side of the model domain in the negative x-axis direction. * ``i1`` is the number of cells of PML to use on all sides of the model domain (can be set to zero to completely switch off the PML), or ``i1`` is the number of cells of PML to use on the face of the model domain nearest the origin of the x-axis (xminus).
* ``i2`` is the number of cells of PML to use on the side of the model domain in the negative y-axis direction. * ``i2`` is the number of cells of PML to use on the face of the model domain nearest the origin of the y-axis (yminus).
* ``i3`` is the number of cells of PML to use on the side of the model domain in the negative z-axis direction. * ``i3`` is the number of cells of PML to use on the face of the model domain nearest the origin of the z-axis (zminus).
* ``i4`` is the number of cells of PML to use on the side of the model domain in the positive x-axis direction. * ``i4`` is the number of cells of PML to use on the face of the model domain furthest from the origin of the x-axis (xplus).
* ``i5`` is the number of cells of PML to use on the side of the model domain in the positive y-axis direction. * ``i5`` is the number of cells of PML to use on the face of the model domain furthest from the origin of the y-axis (yplus).
* ``i6`` is the number of cells of PML to use on the side of the model domain in the positive z-axis direction. * ``i6`` is the number of cells of PML to use on the face of the model domain furthest from the origin of the z-axis (zplus).
* ``i1 i2 i3 i4 i5 i6`` may be set to zero to turn off the PML on a specific side of the model domain. * ``i1 i2 i3 i4 i5 i6`` may be set to zero to turn off the PML on a specific side of the model domain.
For example to use a PML with 20 cells (thicker than the default 10 cells) on only the z-axis sides of the domain use: For example to use a PML with 20 cells (thicker than the default 10 cells) on only the z-axis sides of the domain use:
