[mesa-users] Element diffusion and Gravitational settling for gamma > 1

[Aron.Michel at physik.uni-wuerzburg.de]

Hello everyone,

apparently the last E-Mail got a little messed up. So i decided to send the E-Mail again without using HTML syntax. The following part is the text of the original E-Mail.

I am wondering about the current status of diffusion and gravitational settling for Coulomb coupling parameters gamma > 1. In the instrument paper (section 5.4) it is mentioned, that the physics implementation for diffusion is currently limited to regions with gamma < 1. I already searched the mail archive and found the following E-Mail on that subject:

http://sourceforge.net/mailarchive/message.php?msg_id=27101204

However the default values for the parameters diffusion_gamma_full_on and diffusion_gamma_full_off in the controls inlist are set to 40 and 50, respectively. Therefore i am not sure, if the treatment for gamma > 1 is now available or if the default settings for the gamma-cut off are just not consistent with the restrictions of the algorithm. I am also wondering, which modifications would be necessary to allow the treatment of diffusion for gamma > 1, if it doesn't work already.

Cheers,
Aron
