(

CCTK_ARGUMENTS

)

Initialize the field's data using the chosen metric.

This function initializes the \(\alpha\), \(\vec{\beta}\), \(\gamma_{\mu\nu}\), and \(K_{\mu\nu}\) ADM elements needed for geodesic evolution.

• The chosen metric is managed by the parameter file using KEYWORD parameter 'metric'.
• Any extra parameter is introduced using the size 10 double 'metric_params_d' and integer 'metric_params_i' arrays.
