Detailed Description

Recommend an updated resolution \(L_{\rm new}\) based on how well the shape of the apparent horizon is resolved in terms of its truncation error and pile up modes.

Details

The returned recommended resolution \(L_{\rm new}\) depends on the following options:

MinTruncationError: a minimum truncation error \(\mathcal{T}_{\rm min}\)
MaxTruncationError: a maximum truncation error \(\mathcal{T}_{\rm max}\)
MaxPileUpModes: a maximum number of pile up modes \(\mathcal{P}_{\rm max}\)
MinResolutionL: a minimum resolution \(L_{\rm min}\)

The maximum resolution \(L_{\rm max}\) is supplied by the global cache entry ah::Tags::LMax. The value returned for \(L_{\rm new}\) is then determined as follows: The value returned for \(L_{\rm new}\) is then determined as follows:

If \(L > L_{\rm min}\) and \(\mathcal{T} < \mathcal{T}_{\rm min}\), then \(L_{\rm new} = L - 1\)
If \(L < L_{\rm max}\) and \(\mathcal{T} > \mathcal{T}_{\rm max}\) and \(\mathcal{P} \le \mathcal{P}_{\rm max}\), then \(L_{\rm new} = L + 1\)
Otherwise, \(L_{\rm new} = L\) Note that the truncation error is obtained via PowerMonitors::relative_truncation_error, and the number of pileup modes is given by PowerMonitors::convergence_rate_and_number_of_pile_up_modes
