general relativity - How does a mass create the gravitational field of GR?



As far as I understand, and please correct me if I am wrong, but the basic idea of general relativity is that spacetime is curved by matter. What we call gravity is then not a force as per Newton but a consequence of the geometry of space time. It is assumed that there is a gravitational field produced by a mass which bends space time.



So my question is; How does a mass create the gravitational field?
