The table at the top of the Solve tab shows the elliptic solver information such as
the Status (whether it is initialized or has been refined), what Iteration
number has been run, the Dimensions, the Max. Residual and Total
Residual. You can pick the entities you want to solve (i.e., the subgrids) so that only the
entities with a checkmark next to them will be modified.
The Solve panel for structured domains and blocks controls the elliptic PDE-based smoothing
and transfinite interpolation techniques.
The entities can be sorted by any of the columns in the table. Simply click on the header and
the order of the entities changes accordingly. For example, if you wish to sort all entities
by their dimensions, you would click on the Dimensions header at the top of the table.
The direction of the arrow in the header indicates whether the sort is in ascending or
descending order. Pointwise also remembers how you prefer to have your entities sorted. Upon
entering the Solve command, the entities are sorted in the same manner as when you
exited the command.
Note: Keep in mind that Pointwise remembers how entities are sorted in
this table only during the current session. Once Pointwise is closed, the sort order is not
Below the table is the Iterations text field which allows you to specify how many
iterations the solver runs. There are also several buttons for running
the solver, initializing entities, and projecting domains:
- Run: Runs the elliptic solver for the number of iterations specified
for Iterations. Press the Stop button or the stop sign icon
in the lower left corner of the panel to interrupt the solver and stop before reaching the
number of iterations. Note that when solving on a structured block, a yellow circle
icon is rendered in the Display window showing the location of the maximum
Note: When pressed, the text of the Run and Initialize
buttons changes to Stop. Pressing the button a second time interrupts the command
and returns the button to its original state.
- Initialize: Computes the domain or block interior grid point locations
using the transfinite interpolation (TFI) parameters specified in the Attributes
TFI is automatically applied to a grid when it is first created but can be applied manually
any time thereafter as well.
- Project: Projects any grids with database constrained shapes to the
database using the current shape attributes. Note this command is not available for blocks.
The Project button is grayed out if the database is invisible or not available as a
The Examine button is a shortcut to the full Examine function while in the
Solve command. The Function drop down menu shows the available options. For
blocks, cuts are saved as long as the Solve command is active and reset when
OK or Cancel is selected. Close closes the Examine
function and return to the Solve command. For more information about the diagnostic
functions available, refer to the Examine
