Argus One


Argus Open Numerical Environments (Argus ONE) is an advanced graphical preprocessing and postprocessing software that seamlessly integrates with your ground-water models, GIS and work flow. Argus ONE gives you a unified modeling solution for all your ground-water problems. The Argus unique Plug-In Extension (PIE) technology enables anyone to customize Argus ONE as a graphical user interface for their models. Using this technology, many organizations, including the USGS, created customized Argus ONE Plug-Ins as GUIs for their ground-water models.

Right now, Argus ONE users have full-featured PIE GUIs for all the following models available from the USGS and other developers:

  • MODFLOW – Ground-Water Flow Modeling
  • MOC3D – Solute Transport Modeling
  • MODPATH – Particle Pathlines for MODFLOW
  • SUTRA – Saturated/Unsaturated Flow and Heat/Solute Transport
  • PTC – Princeton Flow and Transport Code
  • Subterranean Research Inc. Geostatistics Packages
  • ARC/INFO and ArcView Interfaces

Plug In Now to the New Standard!
Argus ONE is becoming the standard as many organizations, including the USGS, use it for developing new GUIs for their models. So you always have the latest models coupled with the latest GUIs.

Argus ONE is Simple!
Simple to learn and use, Argus ONE is a unique environment that supports diverse types of modeling codes and GIS data. You will never need to learn another modeling system or re-enter the same data for different models. Best of all, you will never need to buy another modeling package!

Argus ONE is Affordable!
For all this functionality, versatility and ground-water model GUIs, you need to invest only once, at a price lower than any MODFLOW-specific software.

Argus ONEhas enabled engineers and scientists in geosciences-related fields to expedite their preprocessing work by two orders of magnitude without having to change their existing numerical models.

Argus ONEenables you to easily and intuitively prepare your data for any modeling package, finite-element as well as finite-difference based. By automatically linking the physical data you enter in GIS layers to grid blocks or mesh nodes and elements, Argus ONE keeps your data reusable. Changing your mesh or grid doesn't require you to re-enter your data. The Argus Open Numerical Environments integrate a variety of tessellation modules including the Argus MeshMaker finite-difference Grids module and the Argus MeshMaker Triangular and Quadrilateral finite-element modules.

The Argus ONE Workplace
In the Argus Open Numerical Environments workplace (Argus ONE), different types of information are created, edited and maintained in separate CAD-like layers. The number of layers is unlimited.

Domain Outline Layers
The domain's outline in Argus ONE is created using on-screen digitizing tools or imported DXF and text files. The outline specifies the domain to be discretized and the desired mesh/grid densities. A domain outline may contain internal discontinuities, river or fault lines and point sources.

Mesh Layers
Triangular and quadrilateral meshes are created in Argus ONE using automatic mesh generation tools. With interactive editing tools, meshes can be easily edited by point, click and drag techniques. Mesh nodes and elements are database objects which can hold an unlimited number of records which are automatically assigned to them from linked Information layers.

Grid Layers
Block-Centered and Grid-Centered Grids are created in Argus ONE using auto-gridding tools. Rows and columns can be manually added and deleted, the grid can be resized and relocated, and blocks are automatically removed to follow the domain's outline. Grid blocks are database objects which can hold an unlimited number of records which are automatically assigned to them from linked Information layers.

Information (GIS) Layers
Information Layers in Argus ONE enable you to incorporate, visualize, and edit the spatial distribution of any physical parameter such as topographical data, material properties, geographical information, initial and boundary conditions, sources and sinks, etc. The data can be automatically assigned to meshes and grids.

Orientation Layers
Background maps can be drawn or imported in Argus ONE into Orientation Layers to facilitate orientation within complex geographical and topological domains. Bitmap as well as vector formats are supported. Arcs, circles, lines and rectangles can be created and copied into other orientation, information and domain layers. Here you also present your model results using Postprocessing tools.

Importing Data in Argus ONE
By importing information from ASCII and DXF files, digitizing from background pictures and using point and click contouring tools in Argus ONE, you describe the spatial distribution of continuous and discrete information and store it in Information (GIS) layers. In Information layers you can store topographical data, material properties, geographical information, initial and boundary conditions, sources and sinks, etc. The information you bring into the Argus ONE workplace can be used to define the domain to be meshed or gridded, to affect the mesh and grid density, and it can also be automatically linked to mesh nodes and elements and to grid blocks/cells.

Argus Open Numerical Environments Import Capabilities
You can import a wide range of information types and formats into the Argus ONE workplace. The different data sources can be categorized into the following main types:

  • DXF and Contours -Import information related to graphic objects such as points, lines, polylines, arcs, etc.
  • GIS Shape files -Import shapes and the information related to them using ARC/INFO ArcView Shape files.
  • Data at X, Y locations -Import information listed at X, Y locations.
  • Meshes -Import meshes created outside of Argus ONE. (Only with Argus MeshMaker Triangular and Quadrilateral mesh modules).

You can use the various Argus Open Numerical Environments' Import file formats to import:

DXF files of:

  • Background maps
  • Information and domain outline contours

ARC/INFO ArcView Shape files of:

  • Background maps
  • Information, coverages and domain outline contours

ASCII Text files of:

  • Information/domain outline contours
  • Scattered data points
  • Finite triangular elements mesh
  • Finite quadrilateral elements mesh
  • Data points on triangular mesh
  • Data points on quadrilateral mesh
  • Data points on a block-centered rectangular grid
  • Data points on a grid-centered rectangular grid
