This panel allows setting observation points in near field. When this option is selected, the following panel is shown:
Observation Points panel
The user can select near field observation points in different ways. The next options are available:

Geometry Types: observation points may be inserted as group that define different shapes. Select the desired type entity and click on Add button to set its parameters. The available Geometry Types are detailed in next subsections. Before adding new elements, check that the Name of the new entity to be added is different of the already existing ones; otherwise an error will be shown.

Observation points: this section contains several options to work with observation points.
 The left list contains all the observation shapes that has been added as observation points.
 The Edit button allows editing an observation points shape selected on the left list.
 The Delete button allows removing the observation entities selected on the left list.
 Use the Delete All button to remove all the observation points shapes on the left list.
 The Export as Text button allows saving all the generated observation points. Every point is defined in a different line by its X, Y and Z coordinates.
 The Import File allows to add a previously saved observation points file. Only .obs files are supported, which are the internal format generated by the application.
 The Export File allows to save the current observation points configuration in a new file. It must be saved as .obs file, which are the internal format generated by the application.
 Check the Hide observation points option to hide the observation points from the main geometry window but without deleting them. Disable this option to show the observation points.
The observation cylinder may be defined as a closed cylinder (circular section) or only a cylindrical sector (arc section). The following parameters are required:

Name: to define the name of this type of observation points. The name must be different of the already defined ones.

Base Center: coordinates where the base of the cylinder will be placed (in the XY plane).

Radius: radius of the cylinder

Height Coordinates: to define the hight sampling rate of the cylinder.

Number of points: define the number of samples to be generated along the height of the cylinder (in the Z axis).

Height: defines the total height of the cylinder.

Angle Coordinates: to define the circular sampling rate of the cylinder.

Number of points: define the number of samples to be generated along the transversal section of the cylinder (in the XY plane).

Initial angle: angle where the first circular sample is generated in the transversal section, in degrees.

Final angle: angle where the last circular sample is generated in the transversal section, in degrees.
New Cylinder parameters
Click on OK button to insert the observation points from the cylinder, or abort the insertion by clicking on Cancel button.
The user can also import the near field points from a text file. This file can then be imported by selecting External File into the Geometry Types combobox. Note that this option imports a file of points, but does not preserve the near field type (i.e. every point is imported as a separate type). In order to preserve the near field type, the Export file and Import file must be used instead.
Open External File dialog
The external file must contain a list of points given by its X, Y and Z coordinates, with every point specified in separated lines.
Click on OK button to insert the observation points from the file, or abort the insertion by clicking on Cancel button.
This option lets you select a line or curve of the main panel and sampling it as observation points. Before clicking on Add button having select the From Curve type, the curve has to be selected in the Geometry panel. As shown in the below figure, the following parametrs are required:

Name: to define the name of this type of observation points. The name must be different of the already defined ones.

Number of points: to specify the number of samples generated along the curve.
Click on OK button to insert the observation points from the curve, or abort the insertion by clicking on Cancel button.

Observation points also may be generated along a virtual straight line sampled between its extremes. As shown in the below figure, the following parametrs are required:

Name: to define the name of this type of observation points. The name must be different of the already defined ones.

Coordinates: the line is defined by its side points.

Initial Point: first extreme of the straigth line.

Final Point: opposite extreme of the straigth line.
Click on OK button to insert the observation points from the line, or abort the insertion by clicking on Cancel button.
New Line parameters
Use this option to generate a parallelogram of coplanar observation points. The parameters required to its shape are:
 Name: to define the name of this type of observation points. The name must be different of the already defined ones.
 Coordinates: the parallalelogram is defined by three points that form its two main axis, so the generated observation entity will be a matrix of Side x Botton points obtained by sampling the parallelogram.
 Side left axis is defined from Point 1 to Point 2.
 Bottom axis is defined from Point 2 to Point 3.
Click on OK button to insert the observation points from the parallelogram, or abort the insertion by clicking on Cancel button.
New Parallelogram parameters
In this window, the user can create a set of observation points laid out in a grid pattern. To do so, the user needs to specify several parameters:

Name: A short name that will be used by the user to identify the created set of observation points.

Constant axis: The normal axis of the plane that will contain the grid of observation points.

Coordinate value: Value of the coordinate of the axis specified in the previous option.
For each of the axes different than the one selected in the Constant axis dropdown list, the user needs to specify the following parameters:

Initial value: Initial value of the coordinate along each axis.

Total size: The total length of the grid of observation points along the axis.

Number of points: The number of observation points along the axis.
Note: The spacing between each pair of consecutive observation points along an axis will be given by the formula spacing = (total size) / (number of points  1). This value will be shown next to the label "Distance btw. points".
New Plane parameters
Isolated observation points may be generated by using this option. The parameters to specify are:

Name: to define the name of the observation point. The name must be different of the already defined ones.

Coordinates: position of the observation point, specified by its X, Y and Z coordinates.
New Point parameters
Click on OK button to insert the observation point, or abort the insertion by clicking on Cancel button.
The observation sphere may be defined as a full closed sphere or only a spherical sector specified. Multiple concentric spheres (or spherical sectors) may be defined within the same entity. The following parameters are required:
