SPheno: Problem with RGE running. Errorcode:-2

[johnny]

Hey Florian,

I have tried to implement a model, which is basically a U(1)+right handed neutrino+singlet extension of the MSSM. This model also features an inverse seesaw mechanism. Everything worked fine until I ran the model in SPheno. SPheno produced the following error:

Code: Select all

 ./bin/SPhenoSO10ZPrimelow LesHouches.in.SO10ZPrimelow 
  Problem with RGE running. Errorcode:          -2
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
STOP Subroutine TerminateProgram

Do you have any idea where this could come from ?

Best regards
johnny

Hi,

the error -2 appears if a running parameter becomes too big (> 10^36). Possible reasons:
- You run into a Landau pole
- A parameter is not correctly initialized and gets some (huge) random value

Cheers,
Florian
