Hello Guo Li,


> 1.How to add alpha decay reaction into net，such as bi209(，a)tl205.
See Description of net format

You can add something like the following to your local .net file:
add_isos_and_reactions(
r_bi209_ga_tl205
)


or 


add_isos_and_reactions ( 
tl 205
bi 209)

How to resolve the two problem?


This error from $MESA_DIR/net/private/net_derivs.f90 indicates one of the isotopes MESA is looking for is not found in the current reaction network. The answer to your first question might be the solution to this question.

Hi all
I am establishing a big hardwired network，but I have meet two problem：
1.How to add alpha decay reaction into net，such as bi209(，a)tl205.
2.When star evolve with the big hardwired network，it will report error "STOP get1_derivs: itab(out1) = 0".
How to resolve the two problem?Thank you!
