The Overset command is used to set up attributes for and to run a remote
overset assembler software such as PEGASUS 5 or Suggar++. No selection is
required as the command automatically applies to all existing blocks. An
additional capability allowing automatic grid adaption is available on the
The table at the top of the Assemble tab shown below displays information about each block.
Specifically the number of fringe, hole and orphan points is listed.
Additionally, the status of each block is also shown, indicating whether or not
each has been run through the selected assembler since last being changed.
The Overset panel provides tools for selecting and setting up attributes for an overset assembler, and running it.
The entities can be sorted by any of the columns in the table. Simply click on
the header and the order of the entities will change accordingly. For example,
if you wish to sort all blocks by the number of orphans included, you would
click on the Orphan 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 Overset command, the entities will be sorted in the same
manner as when you last exited the command.
Tip: There is an Export, Overset option available in the File menu for exporting an overset grid system. This is another route to running your assembler separately from Pointwise or remotely. However, great care must be taken to match the appropriate overset assembler results with a given project file.
The Show frame provides display toggles for each of the primary point types:
Fringe, Hole, and Orphan. These toggles are only available when a block or
blocks are selected in the table and affect only the selection. Rendering of
these cells is persistent outside of the Overset command so that if necessary,
it will be easier to work on problematic areas of the grid while viewing the
points of interest.
In the Adaption Sources frame check boxes are available to choose whether to create sources automatically
for Fringe, Hole, or Orphan points when the assembler is run. By default Fringe
and Orphan are checked on.
A frame is provided to activate and enter settings for running the assembler remotely.
By default Pointwise will launch the chosen assembler software on the local
platform. By toggling open the Run Remote Assembler frame shown above,
remote execution of the assembler is automatically set. Additionally, this
frame provides input fields for entering the Host Name of the remote system
on which the assembler will be run. The Port which will be used to
communicate with Pointwise’s remote overset daemon, the ogaserver, should
also be specified. This port number is determined when launching the
ogaserver daemon. Finally, Test Connection can be used to see if Pointwise
can successfully communicate with the ogaserver. An indication of success or
failure will be written to the Messages window. More details on setup
necessary for executing the assembler locally or remotely can be found in the
Less used options are available in the Advanced frame.
Additional less used features are found in the Advanced frame, shown above,
by toggling it open. Show Assembly Log will write information from the
assembler’s log file to the Messages window. Show Assembly Output will
write information to the Messages window that would normally be written to
standard output by the assembler. Release Assembly Data will clear all of
the overset data currently in Pointwise having been previously imported by a
Run of the assembler. By default all assembler temporary files are cleared for
any new Run. You can force the assembler to start with a previous run’s
temporary files by checking on Retain Previous Assembler Files.
Run, shown in the top figure, initiates the assembler process by first exporting the block
system with corresponding overset BCs to the format necessary for the
selected assembler. By default the assembler is launched on the local
platform, unless the Run Remote Assembler has been toggled open and
necessary settings provided. After executing the assembler, temporary files, which contain the necessary
overset point use data, are imported back into Pointwise automatically. The Stop command
can be used to halt the assembler execution process.
