Getting error while running SPheno

[saiyad]

(After setting the input values to the parameters in the LesHouches.in.Scotogenic file) While running SPheno, I am getting the following error

Code: Select all

NaN appearing in CT_CouplingcFdFdAh                      
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DIVIDE_BY_ZERO IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
STOP Subroutine TerminateProgram

I don't know how to fix it. Hope for your help.
Thanks.

Hi, could you provide an example LesHouches.in.Scotogenic input file? Also, what versions of SARAH and SPheno are you using?

[saiyad]

I am using SPheno-4.0.3 and SARAH-4.13.0.

Even though I cannot reproduce the problem, it might be caused by the names for the blocks for the input values of M_N and Y_N. Try replacing NONEIN by MNIN and YNIN.

I have changed the name of the blocks properly, but still, I am getting the following error while executing the SPheno LesHouches input file.
