Mesh and Model Tools
Right clicking on the node the “Mesh and Model” option, a window will appear with the available tools (Figure 267).
Figure 267 Mesh and Model tools panel
All the tools are described in detail in the following sections.
Show entity
Figure 268 Show entity panel
With this command is possible to show hidden entities in the tree, like Resistivity/Conductivity/IP model. By default only resistivity is shown, and the others are hidden.
Figure 269 Entity selection
Selection a “New entity” it will be created a new Model node in the tree, with empty values (that can be filled with the commands Set to or Clone from ).
Selection a “New entity - Gradient” it will be created a new Model node in the tree, filled with values computed with “Gradient” operator, based on the model that will be selected with the window that will subsequently be shown.
Set to
Figure 270 Set to panel
This option changes the current value of the Resistivity/Conductivity/IP model. Clicking on Set to button opens a new window for selecting the desired Entity Type through the pop-up menu (Figure 271) and then type the desired value in the New Value number box (it is 0 by default). Click on “Ok” to confirm.

Clone from
Figure 272 Clone from panel
With this command is possible to set in the current model an entity from a different node of the tree. The entities can be like Resistivity/Conductivity/IP model/…. It will be asked to specify the “Source” entity (from this or other project opened into the program) and the “Destination” entity (in the current project) where to copy the specified model.
Figure 273 Entity selection
If selection as “Destination” the “Entity” named “New” it will then added to the tree a new Model node.
Negative IP removal
Figure 274 Negative IP removal panel
Due to computation reasons it may happen that some negative IP values will occur in the Model after the inversion processes. It is strongly recommended to delete them through the is option. It is important to not confuse these values with negative IP data, which are acceptable and manageable through the proper options (section Histogram)
Volume Analysis
Figure 275 Volume Analysis panel
This option allows the calculation of the mesh volume (in m3 and %) and the amount of cells (in numbers and %), which have an Entity Type within a specified range. In Figure 276 the volume is calculated with the resistivity comprised between 50 and 240 Ohm*m, which correspond to 11,113.498 m3 (28.8% of the entire volume) and to 11,308 cells (28.13% of the total number of cells).

Delete
Through this option the entire mesh and model project can be deleted (to avoid accidental deletions, a confirmation window will appear).
Figure 277 Delete tool
Import
Figure 278 Import panel
Use this option to import a Mesh and/or a Model file from a DATA files (*.data or *.wDat or *.txt), a Viewer file (*.vwer), or a XYZ file (*.xyz).
Export
Figure 279 Export panel
Use this option to export a Resistivity/Conductivity/IP model, selecting the desired Entity Type through the pop-up menu.
If the “Foreground Only” is checked, the Background Region is not saved to reduce the necessary space. Note that it is important to export the Background Region also if the output file, after some editing, will be needed to be imported again.
It is possible to export a file as a XYZ file (.xyz) or as a EVS file (.xyz or *.fdl).
