| Boolean | useThermalPort (from Accumulation) | false | Is thermal port pressent? |
| Boolean | useV0Input | false | =true, if zero-pressure-fluid_volume input is used |
| Boolean | useComplianceInput | false | =true, if compliance input is used |
| Boolean | useExternalPressureInput | false | =true, if external pressure input is used |
| Boolean | isExternalPressureAbsolute | false | External pressure as absolute pressure? Relative to ambient otherwise. |
