Relevant contents of seismic refraction forward and inversion

Hello, I’m a university student majoring in geophysics. I want to ask you a question: Is there any code related to seismic refraction forward and inversion in simpeg? I would be very happy if you could spare me precious time to answer me.

Hi Hui,
I think that pyGIMLi (https://www.pygimli.org/) might be better suited for seismic refraction than SimPEG. Recent development in SimPEG focused on non-seismic methods.
