Q: Which should I use: Gridgen or Pointwise?
A: The initial release of Pointwise has the core meshing capabilities of Gridgen included. Over the next several years, we will be adding the remaining capabilities as Pointwise is positioned as the replacement for Gridgen. To help you decide which of these two products you should evaluate, please read the following summaries.
Pointwise will be the right choice for the majority of users. It is the future of our meshing products. Choose Pointwise if you want meshing software with a familiar, easy to learn graphical interface and a high degree of automation. Pointwise includes the ability to make structured, unstructured, and hybrid grids. New features in Pointwise that distinguish it from Gridgen are undo, automatic grid assembly, and 64-bit support.
Choose Gridgen if you need one of the meshing techniques not yet included in Pointwise, and you do not mind learning a proprietary graphical interface.
Q: Pointwise lacks a feature that Gridgen has. When will it be added to Pointwise?
A: Gridgen's core capabilities were the first to be implemented in Pointwise. Over time, all of Gridgen's capabilities will be migrated to Pointwise.
Q: What platforms does Pointwise support?
A: Pointwise supports Microsoft Windows XP and Vista on Intel and AMD (32-bit), Linux on Intel and AMD (32-bit and 64-bit), Mac OS X on Intel and PowerPC (32-bit) and SGI IRIX (32-bit and 64-bit). See the Portability page for more details on Pointwise's platform support. Ports to other platforms are in-work.
Q: When downloading Pointwise I get an error about exceeding the maximum number of anonymous users. What does that mean?
A: Our ftp site places an upper limit on the number of simultaneous downloads by users logged in as anonymous. Contact Tech Support at email@example.com or 800-4PTWISE if you continue to experience problems downloading the software
Q: Image manipulation is different in Pointwise than Gridgen. How does it work?
A: Pan the image by holding Shift and the Right Mouse Button. Zoom the image using the Middle Mouse Button. Rotate the image by holding Ctrl and the Right Mouse Button. Keypad rotation works just like in Gridgen. However, you can make the buttons work like Gridgen via options in the Preferences command.
Q: Can I run my Gridgen scripts in Pointwise?
A: Not in the current release. Pointwise's version of Glyph differs from Gridgen's Glyph and backward compatibility has not yet been implemented. You can write scripts for Pointwise, however, using its version of Glyph. Support for Gridgen Glyph scripts will be handled in a future release.
Q: I was a Pointwise Beta tester. How do I install the production software?
A: On Windows, use Add or Remove Programs from the Control Panel to remove the beta version. Then install the production software as usual.
Q: What do the little Xs by menu commands mean?
A: They indicate commands that are grayed-out because they have not yet been implemented as opposed to commands that are grayed-out because they are not applicable to the currently selected entities.
Q: Does Pointwise support 64-bit platforms?
Yes. Pointwise currently supports 64-bit on Linux and Windows.
Q: Why isn't there an icon and list of domains in the List?
A: The Show Domains command is a toggle for global control over the display of domains. Once it is toggled off, the Domain Icon and the domain list will not be shown in the List Panel. To make the domains re-appear in the List, simply check Show Domains in the View menu.
Q: How can I get Alt+RightMouseButton to work with Linux using the GNOME window manager?
A: Change the following GNOME preferences:
Q: How can I draw a closed curve?
A: When you try to draw a closed curve by selecting its first point you'll notice that it can't be selected. That's because the curve hasn't been saved yet so the point technically doesn't exist. There's an easy way out of this catch-22.
IMPORTANT: Just like Gridgen, Pointwise does not like it when you draw connectors that begin and end at the same point. Create two curves instead.
Q: How can I obtain bound copies of the Pointwise user manuals?
A: Pointwise provides PDFs of our User Manual, Glyph Reference Manual, and Tutorial Workbook with each installation of our software. Our Right to Use License allows you to print and/or bind as many copies of our manuals as you need for your reference.
Q: How can I specify TCP/IP ports for the license manager daemon (lmgrd) and vendor daemon (PWID)?
A: Add the port information to the SERVER and VENDOR line respectively in your license file:
SERVER my_server host_ID port_lmgrd VENDOR PWID port=port_PWID # FEATURE Pointwise PWID 16.0 31-dec-2011 1 user_info=CustID=my_ID ......
Once added, you need to restart your license server using this new license file. Make sure the new ports are open and not used by other applications.
