Incorporating dip angle in meshmaker
Hello, I am trying to model a gently dipping aquifer, and am setting up the grid using the online meshmaker utility. The input field called "Angle between Y-axis and the horizontal" is meant to help…

No convergence during CO2 injection into heterogeneous mineralogy
Hello, I am very stuck on a reactive transport modeling project, and was wondering if someone would be willing and able to help me. I have initialized a homogenous (100% quartz) 2-D aquifer system…

Reconciling Flow and Chemical Inputs
Hello, I have a couple questions that are very basic and therefore hopefully rather straightforward for someone to answer. I am just getting started using TOUGHREACT,…

Setting up initial water chemistry
Hello, I am trying to set up a TOUGHREACT model of reactive transport during upwelling of CO2 and salt, starting by emulating the chemistry presented by Zhang et al., 2016 (attached).…

Recharge via time-dependent Neumann & deliverability boundaries in EOS9
Hello, I am trying to model recharge to a shallow aquifer using a 20 m-deep 1-D (1 m x 1m cross-section) iTOUGH2-EOS9 model in which I incorporate the following processes:…

Problem initializing water table at a given elevation in eos9
Hello, In the TOUGH2 manual, it says that an eos9 (Richard's Equation) model can be initialized with a specified water table elevation by setting CWET in REFCO to that elevation.…

Initial/boundary conditions for discharge from spring (ECO2N)
Hello, I am trying to use ECO2N to model a system where salty, CO2-rich water is upwelling into a shallow freshwater aquifer that is horizontal for some distance,…

Big alternating in/out fluxes along sloped water table boundary
Hello, I am using iTOUGH2-ECO2N to investigate upwelling of CO2-laden brine into a shallow aquifer system, but I am having a problem with the initialization of the flow model and would appreciate…
