- Type
This read-only property displays the selected type of probe object. - Location Method
Defines where the probe object is applied. The options for this property vary based on the selected type of probe object. Depending on the probe object type, property options include: - Geometry Selection
Default location setting, indicating that the probe object is applied to a geometry or geometries (X, Y, Z points, edge/edges, vertex/vertices, face/faces, or body/bodies), which are chosen using graphical selection tools. Select the desired geometry, then click Apply in the Geometry field below the location method. This field then displays the type of geometry (for example: Body, Face) and the number of geometric entities (for example: 1 Body, 2 Edges) to which the probe object is scoped. If you select a point using the Hit Point Coordinate selection tool (see Graphics Toolbar), the read-only X,Y, Z Coordinate properties display and show the coordinate locations. - Orientation
This option is available for a number of different probe types. It sets the probe object's coordinate system. Select the desired coordinate system from the drop-down list. - Remote Points
Scopes the probe object to a remote point. Select the desired remote point from the Remote Points drop-down list.
Caution: The application does not support probe objects applied to objects that you have scoped to multiple Remote Points, either directly or indirectly (such as a spring scoped to a Remote Point that is itself defined by multiple Remote Points).
- Boundary Condition
This option is available for the following probe object types: Force Reaction and Moment Reaction probe objects in Structural analyses. Reaction Probe object in Thermal, Electric, and Thermal-Electric (as Heat Reaction) analyses. Radiation Probe objects in Thermal and Thermal-Electric analyses.
When you select Boundary Condition as the setting for the Location Method property, and associated Boundary Condition property displays. Use this property to select a desired boundary condition from the available drop-down list. - Spring
Scopes a Force Reaction probe object to an existing body-ground spring. Select the desired body-ground Spring from the drop-down list. - Contact Region
Scopes Force Reaction, Moment Reaction, and heat Reaction (Thermal analyses only) probe objects to an existing contact region. Select the desired Contact Region from the drop-down list. - Beam
Scopes the probe object to an existing beam object. Select the desired Beam from the drop-down list. - Mesh Connection
Scopes the probe object to an existing mesh connection in the tree. Select the desired Mesh Connection from the drop-down list. The application writes the forces and moments summed from the element nodal forces and moments to the result file. - Surface
Scopes the probe object to a surface, allowing you to study reactions on cutting planes. Select either an existing Surface or Geometry body. - Path
Scopes the probe object to an existing path. Select the desired Path from the drop-down list. Select the desired bodies in the Geometry field as described under Geometry Selection .
- Surface Coating
Scopes the probe object to an existing surface coating. Select the desired Surface Coating from the drop-down list. - Named Selection
Scopes the probe object to an existing named selection. Select the desired Named Selection from the drop-down list. - Results File Item
Scopes the probe object to an item in the results file. Select one of the following Item Types from the drop-down list:
- Summation
Displayed only for Moment Reaction probe objects when Orientation is also displayed. Allows you to specify the summation point where the moment reaction is reported. Centroid: The simple calculated average, unweighted by length, area, or volume. Orientation System; The coordinate system you specified with the Orientation setting.
- By
Harmonic Response Analysis Only. This property displays for the Force Reaction and Moment Reaction probe objects. Property options include: - Frequency
When this option is specified, the Frequency and Sweeping Phase properties display. - Set
When this option is specified, the Set Number and Sweeping Angle properties display. - Maximum Over Frequency
When this option is specified, the Sweeping Angle property displays. - Frequency of Maximum
When this option is specified, the Frequency and Sweeping Angle properties display. - Maximum Over Phase
When this option is specified, the Frequency and Phase Increment properties display. - Phase of Maximum
When this option is specified, the Frequency and Phase Increment properties display.
- Extraction (Force Reaction and Moment Reaction Probes Only)
The Extraction property is only available for Force Reaction and Moment Reaction probes and the property options depend upon the setting of the Location Method property, as described below: - Contact Region
When the Location Method property is set to , the options of the Extraction property include: : For linear contact when you set the Type property to either or , when you specify loads that are uncharacteristically high or low, you could see inaccurate force reactions. : This setting does not support MPC contact (Formulation property set to ). - (Force Reaction probe only): For this setting, the reaction calculations come directly from the contact elements. This results in accurate force reactions even when the contact region overlaps with other boundary conditions, such as other contact regions, supports, etc. In addition, this setting: | Does not support MPC contact (Formulation property set to ). | | Should only be used with Asymmetric contact (Behavior property set to ). | | Requires that either the Contact Miscellaneous property or the General Miscellaneous property be set to in the Output Controls (Analysis Settings). |
Important: In certain rare cases that involve large or concentrated initial interference and/or thermal expansion applications, the reactions calculated by the contact element option may differ from those calculated by the underlying elements. If you experience such as scenario, the underlying element approach is more accurate. Try to tighten the tolerances of the
Newton-Raphson Option property under the Nonlinear Controls category of the Analysis Settings (also see the CNVTOL command) to improve the contact element reaction calculations.
- Mesh Connection
When the Location Method property is set to , the options of the Extraction property include or . These options specify whether to use the primary or secondary geometry as defined by the Mesh Connection object.
- Surface
When the Location Method property is set to , the options of the Extraction property include: (default): The probe examines the elements cut by the plane and only the nodes of those elements which are on positive side (+Z direction) of the Surface construction geometry. : The probe examines the elements cut by the plane and only the nodes of those elements which are on the negative side (-Z direction) of the Surface construction geometry. : Only examines the nodes that lie on the specified plane, as defined by the Surface construction geometry. To make sure the application selects all desired nodes, this setting uses a small internally calculated tolerance.
- Orientation Method
Only displayed for a Joint Probe. Options include and . - Suppressed
Suppresses the probe object when set to . For more information, see Suppressing Objects.
