MODE
The MODE Command  sets up several optimization options
Currently implemented are:
(1) discrete optimization:
mode/discrete/surface_cmo/tolldamage
if this mode is set, refine, smooth, merge will require any operation that involves nodes on the specified surface to result in a mesh whose surface nodes are also members of the surface_cmo.
A mesh object attribute associated with the 3d mesh named discrete_optimize will be created and its value will be the name of the surface mesh object.
(2) error_adaption
mode/adaption_field/field_name
if this mode is set, optimization operations will be based on reducing error.  A mesh object attribute associated with the 3d mesh named 'adaption_field' will be created and it's value will be the name of the field.
(3) reconnection
mode/recon/geom
mode/recon/delaunay
mode/recon/adaption
Setting this mode will determine the criterion used to reconnect the mesh.  The default mode is delaunay and setting mode to delaunay will cause recon to attempt to create a delaunay mesh.  Setting mode to geom will reconnect to increase inscribed radii of elements.  Setting mode to adaption will reconnect to reduce solution error.  Field_name must be set with the mode/adaption_field command.
FORMAT:
mode/discrete/surface_cmo/tolldamage
mode/adaption_field/field_name
mode/recon/geom|delaunay|adaption
 
EXAMPLES:
mode/adaption_field/solution
mode/recon/adaption

All optimization including massage commands that follow will be performed to reduce error in the user defined field solution.
