All you need is to use CFX5. DM and ICEM will be forced upon you
without cost. No need to go through pointy headed pencil pushers at
all.

What I want to know is, how did you guys talk the pointy-headed pencil
pushers into buying a license for DM in the first place?

Subject: RE: [Xansys] [OTHER] ANSYS Design Modeller and IGES import
To add value to the Design Modeler product and hopefully increase
sales, it
would be nice to be able to run it remotely
from within ANSYS.
Example: In Design Modeler you create a parametric model that we might
call
a parametric template. You then bail out of
Design Modeler and make an ASCII file is a list that assigns values to
parameters, like a=1.5 and rad=2.31 and so forth.
You then get into ANSYS and to import a given geometry you run a
command
that might be something like
RUNDM,template_name,ext,input_file_name,ext. This command starts
Design
Modeler, pulls in the model
"template_name.ext", reads the parameter file "input_file_name.ext",
exports
an ANF file, and reads it into ANSYS
automatically.
When it’s all over you’ll have parametrically defined geometry inside
ANSYS.
This would be great for doing
optimization, probabilistic studies, and just varying the geometry and
boring holes through it and all that sort of
stuff. Your optimization or PDS study can make an parameter file and
you
can use this to drive Design Modeler.
This capability would also allow users to import complicated geometry
into
Design Modeler, learn how to use it, and
still use ANSYS for the analysis. As the users get more comfortable
with
the look and feel of Design Modeler they’ll
begin to explore Workbench and the other ANSYS products that share this
type
of GUI.
Can’t see anything wrong with this. I think it would give the
analysis
community a useful new tool that they can use
immediately in their daily work, generate some additional sales for
ANSYS
Inc., and provide an inroad for Workbench and
the other products that represent ANSYS Inc’s future.
Seems like it would take a co-op student about 3 days to accomplish
the
programming needed to do that. Okay, maybe 4
days.
Just a thought.

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.
Insteaden’t think it is
appropriate to
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.
