CLASS code : same values for matter power spectrum between non-linear model and linear model
Posted: October 21 2022
Hello,
by a direct execution " $ ./class params.ini " , I need to generate matter power spectrum with CLASS code, both with linear mode and non-linear mode.
The issue is that I get the same values between both models.
For linear, I have left in params.ini :
I have set for non-linear :
and also tried with :
Is there a way to get a larger difference between linear and non-linear (halofit or hmcode) for matter power spectra ?
Regards
