Calculation for a spectrum of wavelengths #35

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Implement convenient simulation of spectrum, either inside of ADDA, or with
a separate script. Possibly optimize calculation by simultaneous solving
for many wavelength values in one iterative sequence  (should be especially
relevant in case of Rayleigh particles).

Currently Baptiste Auguie is developing R package including ADDA wrapper, which
presumably can be used to calculate spectrum in a convenient way
http://r-forge.r-project.org/projects/photonics/

But I haven't tried it myself.

Baptiste has provided a sample script, which can be easily adjusted to a number 
of scripting languages.

Baptiste's wrapper is available at 
https://github.com/baptiste/adda/wiki/wrapper_primer together with usage 
example specifically for spectrum calculation.

Since this wrapper is simple and can be easily adapted to any needs, 
implementing the same functionality in ADDA doesn't seem useful. The only 
motivation for this is optimization of simultaneous runs, which is, however, of 
low priority.

This is related to issue 54. Overall, there are a number of papers, where 
repeated DDA simulations are optimized:

solver in the discrete dipole approximation: Application to the orientation 
variation of irregularly shaped particles,” J. Quant. Spectrosc. Radiat.

Based on a few user requests (some prefer DDSCAT just it performs spectrum 
calculation automatically), it seems that there is need to provide some basic 
scripts to do basic spectrum calculation. For now, I am leaning towards Bash 
scripts, since I do have a number of them already.

Such scripts can also include a complicated parser (parsing any number of 
specified values, including Mueller matrix or some values from log file) and 
possibilities to submit multiple jobs with qsub and/or run several 
(corresponding to available number of cores) sequential jobs in parallel.

The main problem is to make it robust and user-friendly. This will most 
probably go to misc/ folder.
