科学软件网是一个以引进国研软件,提供软件服务的营业网站,网站由北京天演融智软件有限公司创办,旨在为国内高校、科研院所和以研发为主的企业事业单位提供的科研软件及相关软件服务。截止目前,科学软件网已获得数百家国际软件公司正式授权,代理销售科研软件达一千余种,软件涵盖领域包括经管,仿真,地球地理,生物化学,工程科学,排版及网络管理等。同时,还提供培训、课程(包含34款软件,66门课程)、实验室解决方案和项目咨询等服务。
TOUGHREACT v1.2 is an extension of TOUGH2 that couples chemical reactions to fluid flow. Coupled modeling of subsurface multiphase fluid and heat flow, solute transport, and chemical reactions can be used for assessment of waste disposal sites, acid mine drainage remediation, contaminant transport, groundwater quality, CO2 sequestration, and mineral alteration in *thermal systems. TOUGHREACT can be applied to porous and fractured media with physical and chemical heterogeneity. The model can accommodate any number of chemical species present in liquid, gas, and solid phases. A variety of equilibrium chemical reactions are considered, such as aqueous complexation, gas dissolution/exsolution, and cation exchnage. Mineral dissolution/precipitation can proceed either, subject to local equilibrium or kinetic conditions. Changes in porosity and permeability due to mineral dissolution and precipitation can be considered. PetraSim now includes limited support for TOUGHREACT v3.3, which can be purchased through LBNL. PetraSim currently creates TOUGHREACT v3.3 input files and simulations can be run through the PetraSim interface. To display results, TOUGHREACT output can be converted to PetraSim-compatible CSV files using this Online Conversion Tool.
PetraSim significantly lowers the barriers to TOUGH2 use by freeing the analyst to focus on the model, while automatically handling the complex details of TOUGH2 input and output files.
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。
Integrated Results Visualization
The user can immediately view results. PetraSim includes time history and 3D iso-surface, vector, and contour plots. Data can be exported to spreadsheets or in a simple format appropriate for graphic software such as TECPLOT.
