[Mesa-users] bad dq error

[Jeremy Sakstein]

Hi everyone,

I have a quick question.

This is actually a follow up on my other thread about using other_cgrav
with the ppisn test suite. For some range of masses (50-60) I am finding
that I get an error message as soon as I begin:

create pre-main-sequence model

                                          species  mass           8
 5.5000000000000007D+01

                                                 bad dq          24
-1.0081447620088736D-04

I ran some tests and it appears that the negative dq is insensitive to the
initial mass that I put in.

I looked this up in star_utils.f90 and it appears that this error occurs
because  there is a cell where dq is negative but I am not sure why this is
happening, or what I can do to fix it.

Is someone able to point me on the right track?

Cheers,

Jeremy
