PetraSim is a graphical interface for TOUGH2, T2VOC, TMVOC, TOUGHREACT, TOUGH-Fx/HYDRATE, and TETRAD. These simulators are recognized for their powerful simulation capabilities involving fluid flow and heat transfer in porous and fractured media. The TOUGH2 codes have been applied to problems ranging from Yucca mountain groundwater flow to multi-component environmental remediation.
PetraSim allows the analysts to focus on the model, while automatically handling the complex details of simulator input and results. The TOUGH2 versions of PetraSim include the corresponding simulation software at no extra cost.
