Quick Question - Unit scales #32

Open costa-francesco-01 opened 2 years ago

costa-francesco-01 commented 2 years ago

I would like to implement a model with a low vev (~ keV/MeV), I tried to start with input values of 1e-1, 1e-2 but I can't find any transition, I get this result from both m.findAllTransitions() and m.calcTcTrans():

Tracing phase starting at x = [0.09917074] ; t = 0.0 Tracing minimum up traceMinimum t0 = 0 .................. []

Is the problem due to the small numerical values? Should I re-scale all my quantities? Or do you think it is related to a problem in the implementation of the mode?

(

The model works for values of the vev between 1 and 70, for higher values I get the following error

/home/francesco/.local/lib/python3.8/site-packages/cosmoTransitions/tunneling1D.py:415: RuntimeWarning: overflow encountered in double_scalars r *= 10
