Body of influence issues
 

Hello,

I have been playing around with 'bodies of influence' (BoI)to try and improve my meshing skills. Things work fine when what I am trying to influence is an enclosure around a solid. But when I try to set a body of influence inside the solid it just doesn't seem to work.

Do BoI only work in enclosures?

I tried with very simple geometry. Literally a cube (frozen) and then a larger cube around it. It lets me set the inner cube as a BoI for the outer but when I generate the mesh there is no difference made!

If anyone can shed some light on this/what I am doing wrong I would greatly appreciate it!

thanks

Susan

So, further searching brought up this thread. It answered my problem, now to figure out how to delete this thread...

hi susan,
are you having any idea about FLUID STRUCTURE INTERACTION OF Small micro-hydroturbine, i wnat do simulation of it in cfx ....

Hello,

Im probably not the best person to ask but here is what I know... :-)

What version of ANSYS will you be using? There is a good tutorial on axial rotors in v12 which you should probably work through first. Give it a go and see if it helps. If you have questions after I will try to help!

bhushan - please do not hijkack threads. Start a new thread for your question.

Susan - Your question is probably best asked on the geometry and meshing forum: www.cfd-online.com/Forums/ansys-meshing/

Sorry, I should have thought Glen. I posted the link that answered my question anyway. Should/Can I delete this thread? I coultn see an option to do so.

dear susan & glan ..,
i am new in this site dont kanw much idea about it ,sory for doing that ....and thanx for your suggestion .....you people are online so i wasposted here...
