Bogdan, Eric,
I appreciate your comments about the geometry engine compatibility, issues
of parasolids kernal and royalty. It is more complicated than I originally
thought. However, one question remains in my mind, the choice of buying a
software package and keep paying TECS may not be as economical as it sound.
In theory, the customers should always able to get the latest and greatest
from ANSYS. But we have to put a faith on ANSYS that it won’t re-package its
newly development works and sell as brand new products.
With all of these, the "tokens" fee structure offered by MSC does sound
really attractive. Does anyone know if ANSYS will offer similar option ?

I’m going to back Bogdan up here.
As much as I like a good conspiracy theory, especially if
we can put blame on "evil suit wearing types," I am lucky enough to have
been in the heat of discussions on this topic with ANSYS, Inc. managers and
developers.
Trust me, if there was any feasible way to fix the geometry engine in the
ANSYS product someone would have done it. I don’t think it is appropriate
to go into the details but several of us dug real deep and asked a lot of
sharp, pointy questions and came to the conclusion that a tool like
DesignModeler is really the only way to get modern CAD capability available
to the ANSYS user. The nice thing about DM is that you can use it with
ANSYS as well as Workbench products.
That leaves the issue of cost. Bottom line: the reason why it is so useful
and robust is that it is built on the Parasolids kernal. EDS gets a royalty.
If ANSYS gave it away with every seat then they would bay a royalty for
every one. So either they jack up
the price of ANSYS seats or make it an incremental cost.
I’ve grown fond of this tool, although we are pushing hard for some changes
to the GUI. If you want to see some of the things you can do with it, check
out our article in "the Focus" about it:
http://www.padtinc.com/epubs/focus/common/focus.asp?I=21&P=article1.htm
Please note: I made an error in the article. At one time you could create
components in DM that carried over to ANSYS. That didn’t make this release
because of some other issues so we have to wait till 8.1 for that.

The new Design Modeler is the former AGP with a new name and a few
developments. It is a long discussion, but the actual ANSYS geometry engine
is rather old (XOX if my memory do not fail me) and lack performance. This
new is a parametric based geometry engine, and the plans were that in finite
amount of time it will replace the actual one. The same geometry engine
(AGP) is used for all WorkBench products, and using them you cannot avoid
noticing the ease in importing complex geometries directly from various CAD.
Personally I do not think that the new developments in AGP (or Design
Modeler) can be implemented in the old geometry engine.

This sounds like another creative way ANSYS uses to generate sales. Instead
of implementing improvements to existing products we already paid, they ONLY
put it in a "new and better" product. Time to call my broker to get few more
ANSYS shares.

Just a passing observation. I’ve recently acquired a license for ANSYS
Design Modeller (DM) and whilst I’m right at the bottom of the learning
curve, I have noticed that in a couple of cases it has imported geometry,
received in IGES format, without problem whilst classic ANSYS failed on both
occasions. The ability for DM to write an ANF file means that I can then
bring the geometry into classic ANSYS.
