# Apparent issue in geodesic solver

Attempted to solve geodesic equations in FLRW metric for peculiar velocities.

WHAT HAPPENED?

Attempted to solve geodesic equations in FLRW metric for peculiar velocities.

geodesic solver gives out of domain errors for 1st point no matter how I tweak the code. Current copy of the work book has been altered to flat Minkowski space and still gives domain errors.

HOW DID THIS DIFFER FROM WHAT YOU EXPECTED?

I can't figure out the error. The Minkowski space case should be a piece of cake and produce no errors as far as I can tell.

Thank you. I changed the worksheet to public unlisted.
