[mesa-users] mesa release to synch with new MESA SDK release

[Warrick Ball]

Hi,

I just tried to update to revision 4849 with

> svn co -r 4849

and I get the error

Updating '.':
svn: E160006: No such revision 4849

I tried pinging mesa.svn.sourceforge.net and that worked fine.  I tried 
updating to the current version and that seemed okay (but might not 
involve checking anything online).

> svn up -r 4798
Updating '.':
At revision 4798.

I Googled the error number but didn't find anything useful.

Cheers,
Warrick

Hi,

This new mesa version (4849) has the few small changes to makefile_header 
required to make it work with the new MESA SDK.

There is also a fix provided by Josiah Schwab to allow relax composition 
to work from an arbitrary starting model number rather than only from 
model number 1.

We've added control parameters to set lower limits for rotational 
distortion corrections factors FP and FT.  The old hard-wired limits were 
0.6 for each; now the defaults are higher (corresponding to less geometric 
distortion):

             FP_min = 0.75
             FT_min = 0.95

I'm working on element diffusion using the beautiful work of Haili Hu and 
collaborators as a guide. Hopefully this will let us support radiative 
levitation in a future release, but we already have an option to use 
atomic diffusion coefficients according to Paquette et al. (1986) instead 
of assuming pure Coulomb.   The default is still to use pure Coulomb, but 
you can try using the Paquette coeffs by setting 
diffusion_use_pure_Coulomb = .false.

For a preview of where we are headed with element  diffusion, take a look 
at this 2011 paper

   Haili Hu, C. A. Tout, E. Glebbeek and M.-A. Dupret,
   "Slowing down atomic diffusion in subdwarf B stars: mass loss or turbulence?",
   Mon. Not. R. Astron. Soc. 418, 195–205 (2011)
