rotating mesh
hi all,

can anybody tried rotating mesh in STAR-CD. pls help me.

Re: rotating mesh
Take a look to tutorial 7. There is all you should know about it.

Re: rotating mesh
hi janocha,

thank u for ur suggestion. but i need rotation of solid domain. in tutorial 7 they mentioned about the fluid domain only.

Re: rotating mesh
so you just rotate the solid cells,

are you doing rotating transient conjugate heat transfer then?

Re: rotating mesh
One important thing,

Why you want to rotate solids? There is no need to rotate solids, since in STARCD only temperature is calculated in solids. So it does not make any difference whether it is rotating or not. You have to silulate that rotation by some other way. Study what happens actually by rotating that solid. E.g by rotation due to friction some heat is generated. Do not rotate the solid, add heat source at proper location; thats it.

lol that was kinda what I was getting at......

Re: rotating mesh
Why cant you just ask the question on here?

Re: rotating mesh
pls ask questions here. Since somebody else may also reply your query.

Re: rotating mesh
hi carno,

1.first of all let me know how to preprocess the rotating case (with solid body rotation)? there no difference between with & without the rotation of solid body? because i am going to do some conjugate heat transfer then.

thank u in advance.

Re: rotating mesh
Im still not sure what you are trying to do, are you interested in the heat transfer between (and in) the solid body and the fluid?

manohar July 6, 2005 06:42

Re: rotating mesh
hi ben,

yes. i am going to do some heat transfer analysis also. but first of all let me know whether star-cd is capable of rotating the solid domain or not?

Re: rotating mesh
star will spin whatever you tell it to spin, solid, fluid , animal, vegetable, mineral

Re: rotating mesh
hello ben,

then tell me how to do.

Re: rotating mesh
do the tutorial, then read the manual then go on the moving mesh training course.

Setting up a moving mesh is fairly hardcore and its not something you will be able to do quickly or easily, explaining the methodology on here is not likely to get you far either.

Presumably you have read the chapter in the manual about moving grids so you know how complicated they are!

Re: rotating mesh
Hi Manohar,

First of all you should clearly explain what you are interested in. Your sense of language seems to be very Poor. Don't get exited if you are not getting proper reply.Above all there is no shortcut to success.

Tell me What do you want to do? You can contact me at the e_mail ID mentioned herewith.
