Olsson's interphase condition (OIC) is carefully examined and scrutinized with respect to both physical and mathematical implications. It is a genuine initial value problem statement so that its full compliance is mandatory for analyzing time-dependent cavitation problems in the journal bearing. Implementation of OIC must include: (1) an unambiguous description of the initial state of the entire fluid film of the bearing, (2) a realistic description of fluid supply configuration, (3) accurate determination of the locations of the void boundaries together with the corresponding pressure gradients, and (4) a suitable morphology model for the cavitated fluid. A new computation algorithm is proposed for cavitation studies that are governed by cross-boundary interface continuity (CBIC), which is a modified statement of OIC.
