This item pops up a window which allows you to set operator attributes for index select operators. If you select a plot that has an index select 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 index select 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 index select 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.
The
Index select attributes
window looks like
Index select 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 index select operators. The window includes controls to manage index selection for 1D, 2D, or 3D.
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.
The index select operator performs a logical subsetting operation on a structured mesh. These radio buttons allow you to indicate for how many dimensions you want to specify mesh subsetting.
The index select operator allows you to specify a logical subsetting operation on a structured mesh by specifying a minimum index, a maximum index, and an increment for each logical dimension of the mesh. For example, if you have a 2D mesh, and you want only to show mesh lines for every other zone, you would specify the starting zone number, the ending zone number, and the number 2 in both text fields which are made active (not grayed out) when you select 2D in the Dimension radio buttons.
The All , Block , and Group radio buttons allow you to control index selection on multiblock meshes.
If your mesh is made of multiple blocks, each with independent logical indices, you can select an index range within a single block by selecting the Block radio button and entering the block number in the Block text field. In this case, the index values you specify are "local" to this block.
If your mesh is made of multiple groups, each (possibly) composed of multiple blocks with sequential logical indices within a single group, you can select an index range within a group by selecting the Group radio button and entering a group number in the Group text field. In this case, the index values you specify are "global" across blocks (although local to the group).
If you instead choose All , the same index range will be selected from every block or group, in the "global" indexing scheme, if possible. This is the value you should choose for single-block meshes.
