[mesa-users] Help with "net_reaction_filename"

[Ehsan Moravveji]

Thanks Bill for your directions.
This time, it worked fine, as expected, but the evolutionary track that I get along the main sequence is wrong. Please take a look at the attached HRD: purple dot is the ZAMS, and I terminated that once center_h1 dropped below 0.50
To get this track, I used the attached abundance list and burning net. Any inlist would do. The abundances perfectly add up to 1.0
Apparently, MESA did not really appreciate my changes.
What are the other steps that I must take to get the evolution right?

Best regards,

Ehsan
