Multiple Conceptual Models
• Dual porosity, leakage (from above and/or below), well-bore skin (enhancement or damage)
• Flow dimension capability allows for interpretation/analysis of non-radial flow such as fracture systems

Numerical Simulator
• mView has a complete set of tools for generating 2D and 3D finite difference and finite element grids.
• Grid properties and boundary conditions can be set using a variety of tools for index selection (e.g., nodes falling inside/outside 2D polygons), boolean logic, and node to element to face conversions.
• mView provides support for delineating discrete fracture features on a rectangular model grid. Given a three-dimensional polygon representation of actual fractures, mView will calculate the element faces that optimally represent the fractures.
• Model specific input files can be generated for TOUGH, HydroGeoSphere, FLAC3D, MODFLOW and others.

Analysis of Model Results
• Compensates for non-ideal test procedures such as pumping rate changes
• Allows incorporation of long-term pre-test pressure histories
• Supports combinations of conceptual models not supported by analytical techniques (e.g. dual porosity aquifer with leakage)

Advanced Graphical Analysis Techniques
• Derivative plots, decline plots, pulse/slug and flow dimension analysis
• Advanced derivative calculation for noisy field data
• Time and space superposition

Optimization (Inverse Modelling)
• Automatic fitting of field data with Levenberg-Marquardt and Simplex methods
• Multiple constraints such as fitting pressure and/or flow data, derivative fits, and fitting results from multiple observations simultaneously
• Advanced statistical processing for confidence region estimation

Sampling
• Latin Hyper-Cube or Monte-Carlo sampling of uncertain parameters can be conducted to determine range and distribution of possible hydraulic parameters that satisfy observations

Data Pre-/Post-Processing
• Extensive facilities for importing, cleaning, and processing field data
• Report-quality 2D and 3D plotting routines
