原文：Two properties are affected when changing fault property values: The permeability (transmissibility) of the litho-type that is transsected by the fault may either be reduced or enhanced by orders of magnitude.The fault property values therefore cause a shift of the existing lithology properties. Entering a value of '5', for instance, means that the initial permeability of the rock is changed by a factor of 10^5. Along faults (vertical flow), this would for example increase the permeability from 10^-2 log mD to 10^3 log mD. Across faults (horizontal flow), the transmissibility would be reduced to 10^-7 log mD. In addition, the capillary pressure of the litho-type transsected by the fault is enhanced or decreased by an absolute value. Entering the value '5' would increase or decrease the initial capillary pressure by 5 MPa. The absolute pressure values are based on experience and empirical data.For both permeability and capillary pressure, entering a value of '0' means that the fault does not change the original properties defined by the litho-type. '10' is the maximum value assignable and defines completely open (Along, vertical flow) or completely closed (Across, horizontal flow) faults.

In short, fault assignment can be summarized as follows:

Open faults: - assign 10 to Transmissibility Along and 0 to Transmissibility Across Closed faults: - assign 0 to Transmissibility Along and 10 to Transmissibility Across

Petromod 中断层开启、封闭性定义规则：
改变断层的属性值会影响两份个参数，即岩性的渗透性及毛细管压力。如果输入5，将使原始岩层的纵向渗透性从10^-2 log mD增加到10^3 log mD，而其对应的水平渗透性将从10^-2 log mD降低到10^-7 log mD。输入0,则不会改变原始岩层的属性。输入10,表示断层在纵向上完全开启，输入－10则表示断层在水平方向上完全开启。
总结：
·开启性断层：纵向上渗透性值设为10,水平上渗透性值设为0
·封闭性断层：纵向上渗透性值设为0,水平上渗透性值设为10
