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.
