BFC basics
Hi All,
Can anyone suggest me some books about how BFC grid works? I have read Malalasekara: An introduction to CFD. It was good for basics, but no detailes about BFC. Gy. Tegze 
Re: BFC basics
Do you mean Boundary Fitted Coordinate grids? If so, try Thompson´s classic book "Numerical Grid Generation: Foundations and Applications". You can download a free copy from the Mississipi State University website (http://WWW.ERC.MsState.Edu/publications/).

Re: BFC basics
If I recall correctly, you guys use PHOENICS at FETI. The appropriate link, therefore, would be:

Re: BFC basics
Thank you very much! "Numerical Grid Generation: Foundations and Applications" is exactly what I was searching for.

Re: BFC basics
Thank You! I have already read it. I am planning to simulate optical fiber drawing for my PhD thesis. I am looking for the best way to simulate radiative heat transfer. I would like to implement DOM or Finite volume (control angle) to PHOENICS. Has anybody tried it yet?

Re: BFC basics
Hi Gyorgy,
We (at the Solar Facilities Research Unit, Weizmann Inst. of Science, Israel) had implemented a control angle RTE solver coupling to PHOENICS for simulation of volumetric solar receivers. Rami 
Re: BFC basics
Hi Rami, Cartesian or BFC grid did you use? In your opinion what is the best way to handle control angle overlap?
Gyorgy 
Re: BFC basics
Hi Gyorgy,
o We use BFC grid. o We treat control angle overlap by the socalled "pixelation method". I can't claim it is "best", but it makes sense theoretically and it works fine. 
Re: BFC basics
Hi Rami, Can you suggest me some papers about "pixelation method"
Thanks, Gyorgy 
Re: BFC basics
The original paper is J.Y. Murthy and S.R. Mathur, "Finite VolumeMethod for Radiation Heat Transfer Using Unstructured Meshes", J. Thermophys. Heat Transfer, V12 N3, pp. 313321, 1998.

Re: BFC basics
Thank you!
It is a very useful article. Gyorgy
