Modeling two ducted fan
 

Hello everybody,
I'm trying to model two parallel ducted fan in Turbo grid in order to analysis in CFX. How could I define geometry in TGrid?

Any suggestion is very welcomed,

tgrid is for meshing... use ansys designmodeler

TGrid != Turbogrid

You can import points into turbogrid.

Thanks dear Ali and dear Stuart for your attentions:)

I know about process of creating Geometry and meshing, I just wanna to know about defining B.Cs. Should I use multiple reference frames to model two rotating fan in CFX or what?

How do you create points for turbogrid?

But this has nothing to do with Turbogrid !!! It is CFX related issue.

Yes you need to define Multiple reference frame to model them. Both are rotating in opposite direction to each other. Now you should decide which type of interface you need: mixing plane, frozen rotor or sliding mesh....


PS: Some one should clarify Tgrid is Tgrid or turbogrid.

Dear Far,
Thank you in advance for your clear answer!
I should excuse all for bad explanation of my issue, I did not know anything about Tgrid and just used this phrase to summarize Turbogrid!
Now, I want to define geometry by importing airfoil points in some sections.

Send your email and I will send you some related material.

@Far:

Tgrid is a Fluent native unstructured tetra + prism volume mesh generator (with other cool features such as shrinkwrap etc.)

Turbogrid is a specialised structured grid generator for turbomachinery geometries (e.g. from Bladegen)

They are very different programs, and definitely not interchangeable!

Hi Stuart23

Name of forum has been changed to Turbogrid
