Category	Properties/Options/Description
Scope	Scoping Method, options include: Geometry Selection: Default setting, indicating that the condition is applied to a geometry or geometries, which are chosen using a graphical selection tools. Geometry: Visible when the Scoping Method property is set to Geometry Selection. Displays the type of geometry (Body) and the number of geometric entities (1 Body, 2 Bodies) to which the condition has been applied using the selection tools. Named Selection: Indicates that the geometry selection is defined by a Named Selection. Named Selection: Visible when the Scoping Method property is set to Named Selection. This field provides a drop-down list of available user-defined Named Selections. You may wish to review the Mechanical APDL References and Notes at the bottom of the page for specific command execution information regarding these selections.
Definition	Criterion: Options included Energy and Box. Energy If Energy is selected, you need to enter an Energy Coefficient. Energy Coefficient: This criterion checks the strain energy of any element that is part of the defined component using the following calculation. A component is defined as the assembly of all scoped elements. where: E_e = strain energy of single target element. c₁ = user input energy coefficient. E_total = total strain energy of the component. NUME = number of elements of the component. If this criterion is satisfied at an element, the program refines the element. A smaller Energy Coefficient improves the potential to trigger the mesh regeneration for the same loads. Box If Box is selected, the following additional properties require entries: Coordinate System (default is Global Coordinate System): defines the minimum values of the box. Length X: defines the diagonal length on global X axis. Length Y: defines the diagonal length on global Y axis. Length Z (for 3D): defines the diagonal length on global Z axis. All the following common criteria properties are available for all Criterion property options as well as 2D analyses: Check At: Options included Equally Spaced Points or Specified Recurrence Rate. Value: This property further defines the Check At property. The default value is `1`. Time Range: options included Entire Load Step or Manual. When specified as Manual, you need to enter a Start Time and End Time. The End Time value must be larger than the Start Time value. Suppressed: Include (No - default) or exclude (Yes) the condition.

Definition

Criterion: Options included Energy and Box.

Energy

If Energy is selected, you need to enter an Energy Coefficient.

Energy Coefficient: This criterion checks the strain energy of any element that is part of the defined component using the following calculation. A component is defined as the assembly of all scoped elements.

where:

E_e = strain energy of single target element.
c₁ = user input energy coefficient.
E_total = total strain energy of the component.
NUME = number of elements of the component.

If this criterion is satisfied at an element, the program refines the element. A smaller Energy Coefficient improves the potential to trigger the mesh regeneration for the same loads.

Box

If Box is selected, the following additional properties require entries:

Coordinate System (default is Global Coordinate System): defines the minimum values of the box.
Length X: defines the diagonal length on global X axis.
Length Y: defines the diagonal length on global Y axis.
Length Z (for 3D): defines the diagonal length on global Z axis.

All the following common criteria properties are available for all Criterion property options as well as 2D analyses:

Check At: Options included Equally Spaced Points or Specified Recurrence Rate.
Value: This property further defines the Check At property. The default value is 1.
Time Range: options included Entire Load Step or Manual. When specified as Manual, you need to enter a Start Time and End Time. The End Time value must be larger than the Start Time value.

Suppressed: Include (No - default) or exclude (Yes) the condition.
