The table at the top of the Dimension panel shows a summary of dimension changes you have made. This is particularly important for structured grids,
where opposite edges of domains and opposite faces of blocks must remain dimensionally balanced. Pointwise automatically propagates dimension changes through
a structured grid when it can determine how to redimension the opposite edge of a domain. This works when the edge consists of only one connector.
Tip: Dimension changes to structured grids are automatically propagated as far as possible.
If there is more than one connector on an edge, Pointwise cannot determine how to divide the dimension change between the connectors that compose the
edge. In cases such as this, it will stop and prompt you to change the dimensions yourself, at which point it will continue automatic propagation as far as it
The Dimension panel keeps track of changes you make to connector dimension to make sure structured grids stay in balance.
The top row of the table shows how many connectors are currently selected for dimensioning. The connectors will also be highlighted in the Display
window. The example table shown in the figure above indicates that three connectors are being redimensioned. Note, if you select a connector that is part of a
structured domain the table may show multiple connectors selected when you only explicitly selected one connector. This is because Pointwise has recognized
that the dimension of the additional connectors will have to be changed to keep the structured domain dimensionally balanced if you change the dimension of
the selected connector.
Note: Use the Reset to Last Balanced button in the Grid, Dimension command to return structured domains to a valid
state if you get confused about how to set connector dimensions.
The next two lines of the table show the number of grid points and the average grid point spacing on the selected connectors. This information is provided
for reference and to help in determining the new dimension. The next full width row in the table shows whether the structured grid portions of the grid system
are dimensionally balanced. The example in the figure above shows a dimensionally balanced case. If the system is not dimensionally balanced, this row will
show the number of structured domains that are out of balance, i.e. inconsistent as illustrated in the figure below.
Structured domains that become out of balance (inconsistent) are shown in the middle portion of the table in the Dimension panel.
The table rows below this show the number of connectors still with their initial dimension, with dimensions set automatically by Pointwise while also
automatically balancing structured domains, and with dimension set by user input. The bottom portion of the table shows information about the connector under
the cursor and any other connectors that will have their dimension automatically set if you change it.
Below the table are two buttons: Reset to Last Balanced and Dimension. Reset to Last Balanced changes connector dimensions back to
the last state where all the structured domains have equal number of grid points on opposite edges. This can be useful if you get confused during the
dimensioning process and are not sure how to get to a balanced state. Dimension sets the number of grid points on selected connectors based on the
