TOUGH2 Enhancements
PetraSim 2017 has added several new features that give improved support for geothermal simulations. These include updates to the TOUGH2 simulator to support updated steam tables, improved well boundary conditions, and more.
All EOS module executables are optimized and integrated into PetraSim, so no further compilation is required. The user clicks and runs. If you have developed a modified variation of TOUGH, support is provided to pre-process and post-process those results also.
利用PetraSim解决具有挑战性的地下水流问题。
PetraSim是一个用于TOUGH2仿真器的图形界面，它由Lawrence Berkeley National Laboratory开发。流体在孔隙和裂隙介质传热中，TOUGH2和它的软件具有强大的模拟功能。TOUGH2代码解决的问题包括从Yucca山地下水流到多元环境整治等。PetraSim通过一个交互式的3D环境，使建模者能够访问TOUGH2的功能，包括网格生成、参数定义和结果显示。
3D建模
PetraSim全面支持3D建模。用户可以导入现有的3D层数据，并使用它来定义几何模型。用户可以将材质属性分配给层，并通过模型定义矿井。
网格生成
PetraSim支持多个网格选项。基本的是一个矩形网格，在这个网格中，矿井根据所在的区域分配属性。这个网格提供了可靠的收敛特性。如果希望网格与层一致，则可以使用矩形或Voronoi一致网格来完成。
支持TOUGH EOS选项
已经针对许多不同的状态方程（EOS）开发出了相应的TOUGH代码。例如，EOS3描述了在单一或两阶段条件下可以存在的水和空气，可以用于地下水或地热应用。EOS7C包括甲烷-二氧化碳或甲烷-氮气体混合物。应用包括地下地质碳封存地点和天然气储藏库。所模拟的组件包括水、盐水、非冷凝气体（CO2或N2）、气体示踪剂、甲烷和热量。
TOUGH2-MP is a massively parallel (MP) version of the TOUGH2 code, designed for computationally efficient parallel simulation of isothermal and nonisothermal flows of multicomponent, multiphase fluids in one, two, and three-dimensional porous and fractured media. In recent years, computational requirements have become increasingly intensive in large or highly nonlinear problems for applications in areas such as radioactive waste disposal, CO2 geological sequestration, environmental assessment and remediation, reservoir engineering, and groundwater hydrology. The primary objective of developing the parallel-simulation capability is to significantly improve the computational performance of the TOUGH2 family of codes. The particular goal for the parallel simulator is to achieve orders-of-magnitude improvement in computational time for models with ever-increasing complexity.
