Description file for manual decomposition

A.Devesa · March 30, 2010, 09:39

Hi all,

i am trying to decompose my domain which is rotation-symmetric into more than 4, let's say 8, equally big regions. I guess the only way to have a pie-like distribution along the rotation axis (preserving hence the symmetry) is to use a manual decomposition.

The manual decomposition in my case would just depend on the cylindrical coordinates of my cell centers. Nevertheless, i can't find any utility saving just the cell-center coordinates in the same order as would be done by setFields for example, so that i can directly manipulate them in a cellDist-like file for my manualCoeffs.

Has anyone already worked directly on cell-center coordinates for a manual decomposition or something in this direction? I'd be grateful for any tips.

Solved via setFields and new type of cellSources "portion of cylinder"...

Hello,

Very interesting. I am in a similar simulation. Can you give me some more explanation how you did this exactly?
