建立起CO2水岩反应双孔双渗模型，孔隙度有变化，渗透率无变化，检查模型发现未耦合应力模块，请问如何实现基质、裂缝分别设置不同应力敏感模型，有没有对应的双孔双渗案例参考

首先，渗透率变化和耦合地质力学没有关系，孔渗相关性需使用RFCALC等关键字，同时手册里面说明了对于结果中渗透率不会随之发生改变，，而是使用rf因子。
It is important to note that change is permeability due to solid deposition; mineral precipitation or dissolution; or due to aqueous phase adsorption is accounted for in flow calculations by the phase resistance factors which can be visualized using *OUTSRF *GRID *RFO *RFG *RFW or corresponding special history keywords in the input/output section. The permeability value itself remains unaffected and therefore user will not see any change in permeability while visualizing.
基质和裂缝使用不同的地质力学模型，可以实现，使用GEOTYPE分区定义。gmgmc009.dat
