-
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, the
Location 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 .

Objects.

- Result Selection
The options for this property vary based on the selected type of

or . - Spatial Resolution
When edges, vertices, faces, or bodies are selected as the Geometry,
this property displays. It allows you to calculate the maximum

Minimum) result values across the given geometry
selection. - Result Type
This property provides a list of available results for a Joint
