Problem with y0 > b b~ decay in gridpack generation with DMsimp_s_spin0_4f model

Hi,

My guess is that this is a problem with the compilation when compiling in multiple core.
Similar problem have been fixed in more recent version of the code.

My suggestion would be one of the following
1) to just relaunch the code, since the compilation conflict is likely to fix itself at the second compilation.
2) you can also compile by hand and/or force the compilation to run on a single core.
3) use a more recent version of the code

Cheers,

Olivier

Hi,

Thanks for the quick response. I will give that a try
