<- [[:programming]] ====== base flow and fluctuations? ====== //Emmanuel Germaine, 2009-02-10 07:47 // I was working with the channel flow code V2.1.2. Last week, I have installed the latest version available on the wiki. 1.3.3. It seems that this version does not generate the same results than the previous that I used. If I save the velocity field using : FlowField u(Nx,Ny,Nz,3,Lx,Lz,a,b); ... for(int nz=0;nz<u.Nz();++nz){ for(int ny=0;ny<u.Ny();++ny){ for(int nx=0;nx<u.Nx();++nx){ fileName << x(nx) << ' ' << y(ny) << ' ' << z(nz) <<' ' << ' '; fileName << u(nx,ny,nz,0) << ' ' << u(nx,ny,nz,1) << ' '<< u(nx,ny,nz,2) << endl ; } } } The version v1.2.2 saved an instantaneous field. The new version saves a velocity field that looks centered on zero (there is no mean). I would like to work with the instantaneous velocity field instead of its fluctuating part. Do you know if there is a way to do this ? thanks! ~~DISCUSSION~~
