What new features does Visual MODFLOW 2009.1 support for the new SEAWAT v.4 module?
Visual MODFLOW supports the following new features available in SEAWAT v.4: • A temperature species can now be added when defining a new transport variant, allowing you to simulate heat and solute transport simultaneously. • Simulate the effect that fluid viscosity variations have on resistance to ground-water flow using the Viscosity (VSC) Package. • Simulate fluid density as a function of temperature and one or more MT3DMS species and, optionally, a pressure term. You can also specify one of several non-linear equations to represent the dependence of viscosity on temperature. • A new option in the simulation settings for the VDF package allows for solving the Variable Density Flow (VDF) equation to update the flow field only if fluid densities have changed by a user-defined value. This option can potentially reduce runtimes for simulations in which a new flow solution is not required for each transport time step. • For the Time-Variant Constant-Head (CHD) package, auxiliary variables
