GRHD: Add parameter c2p_dynamic_atm
This adds and modifies the following parameters in the GRHD
section:
- (new)
c2p_dyamic_atm
: Controls whether a fluid-atmosphere interface is allowed to evolve. - (renamed)
c2p_freeze_atm_reset -> c2p_enforce_causal_atm
; also updated the doc string
With c2p_dyamic_atm=true
we now recompute the c2p_atm_reset
mask before determining the c2p_freeze_atm
mask.
Previously, we only ever ran with the false
option, which would mean that we artificially imposed the interface as it was given in the initial data.
