5. Conclusions In this study, the simulation of the fluid flow has been investigated using a LISA FE-based simulator. LISA provides the user with new software for fluid simulation in rocks using transient porous analysis. It can be used to solve many different problems, including structural, thermal, and fluid problems. Our unique capability and primary purpose are to consider flow in fractured rock. In such a problem, flow is highly dependent on fracture opening, which in turn is a function of contact stress and thermal deformation. Hence, Franc2D was used to simulate the crack path based on the fluid pressure. The crack direction was verified with experiments from the literature. By considering the fluid direction from LISA (i.e., velocity map) and fracturing from Franc2D, the location of cracks and direction can be estimated. 6. References A.M. Al-Mukhtar. 2011.
