[mesa-users] Creating model grids with frequencies

Hi MESAlians,

I'm about to try to use MESA to construct some model grids with 
oscillation frequencies.  I thought I'd ask if anyone has already 
developed tools for doing so before I try my own thing.  That is, just as 
one would have a collection of evolutionary tracks, for e.g. different 
metallicity, with, say, Teff, L and other observables, I'm going to 
construct grids that have oscillation frequencies, too.

My basic strategy will be to start with the "pulse" test case.  I'll 
modify the inputs in the code for the desired ell and frequency ranges, 
then tinker with the ADIPLS input files for any other parameters I want to 
fix (e.g. how the normalized mode energy is normalized).  Because I'm not 
master coder, I'll probably just dump the output to some sort of text 
file, of which I'll make sense later, probably in Python.

If anyone can offer some points, I'll be super grateful.  And, by the same 
token, I'll share what I end up doing and where I find any stumbling 
blocks.

(Currently, I've got the output being spewed out for a given evolutionary 
run but I'm not choosing the frequency range wisely and getting a ton of 
stuff on the pre-MS.  I'll probably start from the ZAMS for now instead.)

Cheers,
Warrick
