Orthogonal slice operator attributes menu item

This item pops up a window which allows you to set operator attributes for orthogonal slice operators. If you select a plot that has an orthogonal slice operator applied from the Active plots list in the MeshTV Main window, then anything you change and apply will affect selected plots. Plots not highlighted will not be changed, unless Apply operators to all plots toggle button is on, in which case all plots will be changed. If you select this item without selecting a plot first, and you try to apply changes, a Query window will pop up asking if you want to add an orthogonal slice operator so you can apply the changes you have made. Note that if you make changes in this window and then select a plot that has an orthogonal slice operator applied, your changes will be lost.

You can modify the default settings for attributes for future operators by pulling up this window, making your changes, and pressing the Make default button. This affects only operators applied in the future, not already applied ones, and stays in effect only for the remainder of the current MeshTV session unless you also select Save settings from the File menu.

Orthogonal slice attributes window

The Orthogonal slice attributes window looks like Orthogonal slice attributes , if you are using MeshTV's defaults. If you aren't, the values might be different.

This window allows you to set the attributes assigned to existing or future orthogonal slice operators. The window includes controls to define the axis along which to slice and the location of the slice plane via percent, zone number, or coordinate.

If you don't see a description for an item in this window, check in the Shared items section near the front of the chapter.

Axis radio buttons

The orthogonal slice operator slices through a 3D data set via a plane which is orthogonal to (perpendicular to) one of the coordinate axes. These radio buttons allow you to indicate which axis the plane will be orthogonal to.

Slice by label and radio buttons

The controls in this area allow you to specify how the slice plane moves along a chosen axis. You can select the placement of the plane by Percent , Zone , or Coordinate .

Slice by percent

When the Percent radio button is selected, you can specify the location of a slice plane along the chosen axis by percent along that axis. The slider allows you to select from the range 0 to 100, while the text field allows you to type in numbers within the same range.

Slice by coordinate

When the Coordinate radio button is selected, you can specify the location of a slice plane along the chosen axis by its coordinate value simply by tying the value in the text field.

Slice by zone

When the Zone radio button is selected, you can specify the location of a slice plane along the chosen axis by the index of a zone.

The Logical index radio button allows you to specify a zone in a structured mesh by its i, j, and k indices. If your data is also rectilinear, you need not specify all three indices; for example, if you have the Y axis selected you need only enter a j index. If your data has multiple groups, you must choose one of the groups by selecting the Group toggle button and entering a group number in the Group text field.

If your mesh is unstructured it cannot be accessed using logical indices. For this data type you must select the Zone number radio button.

The Zone number radio button allows you to specify a zone by its sequential index within a block. For example, on a curvilinear mesh with 10x10x10 zones, you can select the zone by its number in the range 0 to 999 (or 1 to 1000 in some datasets). If your data has multiple blocks, you must choose a block number by selecting the Block toggle button and entering a block number in the Block text field. Note, however, that on a rectilinear mesh this number is still a logical index along the selected axis, although it is now local to the selected block.
