Cell Filters are used to control visibility of the cells in the 3D view. Three types of filters exists:

  • Range filter : Define a IJK subset of the model.
  • Property filter : Define a value range for a property to control cell visibility.
  • Well cell filter : Display grid cells that has connections to a well. Controlled from the Simulation Wells item.

All filters can be turned on or off using the toggle in the Project Tree and controlled from their corresponding Property Editor.

Range filters

Using range filters enables the user to define a set of IJK visible regions in the 3D view. A new range filter can be added by activating the context menu for the Range Filters collection in the Project Tree.

TIP: An I,J or K-slice range filter can be added directly from a Cell in the 3D View by rightclicking the cell and using the context menu.

Below is a snapshot of the Property Editor of the Range Filter :

  • Filter Type : The filter can either make the specified range visible ( Include ), or remove the range from the View ( Exclude ).
  • Grid : This option selects which of the grids the range is addressing.
  • Apply to Subgrids : This option tells ResInsight to use the visibility of the cells in the current grid to control the visibility of the cells in sub-LGR's. If this option is turned off, Sub LGR-cells is not included in this particular Range Filter.

The Start and Width labels in front of the sliders features a number in parenthesis denoting maximum available value.
The Start labels shows the index of the start of the active cells.
The Width labels shows the number of active cells from the start of the active cells.

Property filters

Property filters apply to the results of the Range filters. Below is a snapshot of the Property Editor of the Property Filter.

This filter filters the cells based on a property value range (Min - Max). Cells in the range are either shown or hidden depending on the Filter Type ( Include / Exclude ). Exclude-filters removes the selected cells from the View even if some other filter includes them.

A new property filter can be made by activating the context menu for Property Filters. The new property filter is based on the currently viewed cell result by default.
