Meeting Update

Mostly working on turbulence stuff and developing routines for creating random fields using FFT's as well as spectra…

Created Layout objects which allow for a distributed fixed subgrid across all of the processors. There are also routines for loading data from the AMR mesh into the layout and extracting data from the layout into the AMR mesh - as well as transferring data from one layout to another

Created PFFTPlan objects which allow for easily performing parallel FFT's of data. It creates nDim layouts where in the 1st layout there are no divisions in x, in the second layout there are no divisions in y and so on…

Creating spectra processing objects which use PFFTPlans to load various fields from the AMR mesh into a local data array - then perform a parallel FFT - and then bin the results into radial bins and output the results in a curve file. Supports scalar fields (density spectra) as well as vector fields(velocity spectra…) Vector fields output the spectra of each component as well as the spectra of the total, the solenoidal, and the diverging components.

Plans can be used to generate initial conditions much faster than summing up sines and cosines… And layouts should allow to take the data in the base grid - and remap it on to a subsection of a finer level (for using forced turbulence results as initial conditions for a clouds velocity field…)…
