`Flexural isostatic compensation?' (Subsidence Group File) allows the user to specify whether the lithosphere behaves as an elastic plate, with perfect "airy" isostacy, or whether no isostacy will occur. If true (T, t, or true) is chosen, then a flexural rigidity value must be input in the `flexural rigidity' line. You may enter 0 and generate perfect isostacy, or some reasonable value (e.g. 1e23) to have the lithosphere behave as an elastic beam. Note, values between 0 and 1e20 are very weak plate strengths. (simbasin will crash if very weak plate values from ~1 to ~1e14 are chosen)
Figure 11 shows the results of activating flexural isostatic compensation with perfect isostacy Figure 11.a, flexural rigidity=0) and a reasonable plate rigidity (Figure 11.b, flexural rigidity=1e23).
