Default STAR-CAD on windows

Hello all,

We are considering STAR-CAD on windows, we have read the comments from the STAR-CAD director for windows on the website

http://www.cd-adapco.com/news/releases/windows_3.24.htm

Any of you using star-cad on windows? how does it integrate in your design process and CAE methods?

Any advice?

Clive

Hi,

if possible, when ever, I would strongly recommand any Unix / Linux System. In the past there where some problems with Windows-versions (info directly from adapco).

Linux is the developer platform, and because of this, linux is the most stable platform, and the platform which is most tested. In generell it is not a good idea using ported unix / linux software on Windows.

I very often write small unix-shells scripts for automatisms. With the unix programms awk and sed there is a "bridge" to the normal ascii scripts like the StarCD-Macro language (*.MAC, *.inp files). I don't know such possibilities in Windows.

The last one is the most important reason why to use Unix / Linux. In the past (StarCD v3150A) writing such scripts was a need (!!!) in transient calculations an parallel computers (*.pstt > 2 GB, merging *.pst_iter files, automatic restart for wrting out the result cycle (in ignition engines) , automatic postprocessing, automatic image (movie) generation, ...).

A collegue of mine as not any experience with linux, but today he is very glad not to use WIndows.

Don't get unlucky, use Linux.

Thats all very nice hubert but most of the STAR-CAD stuff doesnt run on linux because the CAD packages themselves dont run on linux. I havent used the STAR-CAD stuf myself but it does look good.

If you are interested in CAD integrated CFD, I would strongly recomennd to use the new windows realse 3.24 (use it only on xp 32 not on 64 bit xp ). I don't know your CAD Systems, but I've tested it on proe wildfire. The integration is done by switching a button in your proe environmemt after installation. And that's it.

For CAD integrated CFD I would use the Windows plattform because this is the development-plattform for the most CAD Systems (Pro/e,CATIA V5, Inventor)

p.s. have a look at EFD.Lab from NIKA. It is the best integrated CFD Tools for engineers and for most common application absolut sufficient enough!

efd lab doesnt seem very integrated (i looked at their website) the whole idea of the STAR-CAD stuff is that you dont come out of the native cad environment, meaning that you have parametric modelling as opposed to design cad, export, import, analyse, redesign, export, import........

"I doesnt seem very integrated?"

what do you mean? EFD Lab V5 fully integrated in V5 EFd PRO fully integrated in PROE EFD Lab fully integrated in Solidworks.

You should have a closer look

I see, so it has its own solid modelling package and a native file import from full CAD packages (or am I still missing the section that says it is fully integrated into the PRO/E environment). Either way I would be somewhat wary of anything to do with the people who make cosmos, I had a go with it once and it seemed very poor

Who talks about CAD-Integrated Systems? The Question was just only StarCD on Windows or not.

By thew way, if you want to do real CFD works, a CAD-intergrated tool can't by the the choice, because the automatisms (tet-meshing, no moving mesh) and default solver settings are just good enough for simple cases. For this is is OK, but nor for more. Do you want more? High quality results?

Sorry, I don't realy have problems simply writing out a STL format geometry from the CAD tool -> extract my flow field from it -> and generate a high quality CFD-mesh on it. I realy don't need meshing and solver setup in a CAD-tool with CFD integrated with only restricted possibilities. I don't need that CAD integration.

It really doesn't matter if the CAD-Tool runs on UNIX or Windows to write out that geometry.

An other point: I don't have tested the adapco tools for CAD-integration, but in my opinion StarCD is in generell not a good choice for CAD-integration, because of the complexity. VECTIS by Ricardo is much more suitable for this.

Wait a little bit for StarCCM, where polyhedral meshing is possible with a coupled solver (means: not segregated solver). Then CAD-Intergration with StarCCM becomes resonable.

Hubert, try reading next time, clive mentions STAR-CAD once in the title and three times in the question! Thats who is talking about STAR-CAD.

STAR-CAD is a CAD integrateted system hence why we are talking about it. Your comments about using STAR-CD for CAD integration are off the mark too, if you had ever actuall used STAR-CAD or even looked at the website about it you might realise that it looks nothing like STAR-CD and is a fully integrated front end in the native CAD system, indeed you dont need to go anywhere near PRO-STAR!

(rant in full flow)

And another thing, STAR-CCM+ is also integrated into STAR-CAD so you can use polyhedral meshes with it already!

I have used the STAR-PROE in Windows.

I think the good CAE type CAD is very important.

If you want to use a complex cad to generating a mesh by STAR-PROE, you will get a large number of cell number and take a lot of time.

You still need to create the fluid region in pro/E.

If your geomentry is not very complex, I think that you can use STAR-DESIGN or PRO-MODELER.

================================================== ==

I think that in the some company, people can do a CFD project about 1 month, but in some company people may have to do a simulation in one or two days.

And the automesh tools getting powerful.

So, I think that STAR-CAD is a good tool.
