The MODE Command sets up several optimization options
Currently implemented are:
(1) discrete optimization:
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.
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.
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.
mode/recon /geom delaunay adaption
mode /recon /adaption
All optimization including massage commands that follow will be performed to reduce error in the user defined field solution.
