Hi Genlemen,

I am choosing a grid generation package. I need to simulate a contrifugal compressor impeller with a hole on casing wall. The hole is used to duct flow from midpassage to inlet.

So what I need is a grid generator which is both good for standard turbomachinery geometry and good for some unregular geometry as well. And my solver is Star-CD.

Thanks for your recommendation and have a good weekend.

John

Have a look at Gridpro. Multiblock-Hex-Meshing with mesh-optimisation.

Hi,

You should contact ICEM CFD Engineering:

www.icemcfd.co.uk www.icemcfd.com

Your nearest office will be pleased to help you in your search for the best tool for the job.

I have experience in meshing such models. I feel that ICEM could provide you with a complete tool giving you the ability for multiblock structrured HEX as well as unstructured TET and even hybrid mixing the two types togther. All these meshes can be written direct to STAR CD. ICEM is also a prefered partner in mesh generation for use with STAR CD.

Let me know if you have any further detailed questions.

Regards

David

Hello John,

May I suggest you to contact NUMECA. The grid generator IGG/Autogrid is a multiblock structured grid generator fully dedicated to turbomachinery configurations. It can easily handle standard and unregular geometries, such as the one you are describing. A major feature of Autogrid is that it stores all the mesh parameters into a template file. This means that you can generate automatically the same grid for a given family of geometries. The template stores the mesh properties which are essential in turbomachinery configurations (topology, number of points on LE and TE, size of the first cell in the streamwise and pitchwise directions, number and distribution of points in the main blocks, in the clearances, in the casing holes, etc).

Hope this can help.

Do not hesitate to contact us at NUMECA USA (Steven Sommer 602/231-5913 STSommer@az.rmci.net) or at NUMECA International (+322-6433570) - www.numeca.com

Best regards,

You can also look at TIGER at www.catalpa.net. It allows you to create the standard turbomachinery quickly.

Apart from lots of marketing bla bla ("Simply the world's best turbomachinery grid generation code") and some H-type meshes in the gallery there are no technical information about the code on your homepage.

If you can't deal with O-type or general muliblock topologies then you are more than 5 year behind the time.
