Dynamic Export Templates
You can create dynamic templates like those used by Argus MeshMaker. Dynamically-defined templates are constructed of
script commands and script command arguments that are resolved during the export process. Script commands can invoke Argus ONE expressions thus allowing you full access to the parameters you created while creating your
conceptual model and dynamic links. For instance, if you use the command "Loop over Parameters" (Parameters is the loop iterator) in a script, Argus MeshMaker will loop over the number of parameters (information
fields) linked to nodes or elements in your mesh layer while exporting it and export all of them. Free export templates are available for downloading.
Argus Postprocessing and Graphics
Using the new postprocessing tools, you can present and investigate your model results in the same window you've created your model input. The six new scientific
visualization methods are: 3D Surface, Color Map, Contour Map, Vector Diagram, Particle Pathlines, and Cross Section.
Visualize Model Input and Output
The Argus Open Numerical Environments (Argus ONE) supports postprocessing as well as preprocessing. Argus ONE
is the only pre and postprocessing environment that can be utilized with all numerical models you use and develop.
Being fully integrated within the Argus ONE workplace, these postprocessing capabilities allow you to visualize and investigate your model results in the same
environment you prepare your model input.
Site Visualization
Visualization tools in Argus ONE also allow you to visually investigate the data you prepare using the preprocessing tools
of the application. Thus, for example, you can create a 3D surface describing the nodal values of a geological formation roof, of the bathymetry of a lake, or perform a full site characterization.
Export to All Numerical Models Using Argus ONE
Whether you develop your own numerical models, use public domain models or work with commercial models, Argus ONE enables you to do all your pre and postprocessing
in one friendly environment and export the data you linked to your grid and mesh to all your models. Using the Export Template dialog, you create an export template for each of the models you use and save it to disk. Whenever
you need to export your data to a model, just load the appropriate export template form disk and choose the Export menu. Using export templates, Argus Open Numerical Environments users export their data to different models such
as:
- All USGS public domain models such as MODFLOW, MOC, SUTRA, etc.
- Commercial numerical models such as: COSMOS/M, MATLAB, ECLIPSE, etc.
- Self Developed models.
Export Data to Any Model
Exporting your meshes or grids and all data associated with them to ASCII files for your numerical model is
accomplished using export templates. Each Argus MeshMaker module is equipped with a default export template specifying the default format Argus ONE will export your meshes or grids when you export your project.
Define Your Own Format
Export templates give you full control over your export file format. This enables you to directly export the information
you've created in Argus MeshMaker to any numerical model you use in the exact file format the model requires.
In an export template, you can specify into which files you want to redirect the output, which parameters you need to export, set the delimiters, set the format
of a parameter, loop over nodes, elements and blocks, calculate new expressions during export, set the number of characters in a line, etc.
Define Export Templates for Many Models
You can name each export template you create, save it to disk, and load it when needed. This enables
you to maintain as many export templates as you need for the various models or versions of a model you use.
The export template is created using the Construct Export Template dialog. The template is written in a scrip- like language. You can either use the dialog
buttons to construct an export script, or write an export script in you favorite text editor and load it later into Argus MeshMaker.
Accessing Information Parameters
All the layers you create to store your information are called by their names and are available through menus
so that you do not have to memorize your layer names. The following screen shot shows the Layers menu presenting the available layers and layers' parameters (fields).
Accessing Functions
Argus Open Numerical Environments' graphical user interface enables you to access all functions available through menus
thus reducing syntax errors. Moreover, when you approve an expression, Argus ONE tests the expression for syntax and mathematical errors and informs you of the nature of your error. The following screen shot shows the Functions menu of a grid type layer.
Calculating Complex Equations Using Argus ONE
To easily calculate complex expressions use Argus ONE's expression editor and the abundance of functions supplied. You can calculate the "thickness" of a
geological formation, the mass through an element or a block, the length of a "river" or "fault" crossing an element or a block and the mass it contributes to them. You can also interpolate any parameter
onto a grid or a mesh. Using these powerful tools will save you many programming hours. Argus ONE (spreadsheet-like) expressions can contain Mathematical, Trigonometric, Logical, Search, GIS, Grid, Mesh, Block, Node and Element
functions. To create expressions, use algebraic and boolean operators.
Mathematically Manipulate Your Data
Manipulating your information is easily performed by combining your database structure and the abundance of
functions and operators available through Argus Open Numerical Environments (Argus ONE) expressions. Argus ONE expressions allow you to easily perform math, trig, string, GIS, logical, search and other operations on information
stored in your Argus ONE layers. Argus ONE expressions are also available in the export template thus allowing you even greater control over your output format.
Expressions allow you to compute entities such as:
- Thickness of a geological formation
- Artificial distributions of physical parameters
- Effective mass entering an element, node or block
- Automatically assign boundary condition types and values to elements, nodes, and blocks
- Control element and block size (mesh/grid density)
- Calculate your model's output mass balance
- Calculate your local matrices
- View initial conditions distribution
- Any relation between your information, data, mesh and grid layers
Creating Expressions:
Manipulating your information is performed by creating expressions in the Expression dialog presented below. The expression below calculates the saturation
level in an unsaturated zone based on a retention curve (van Genuchten, 1980), for flow in a vertical cross section.
The following picture demonstrates how a scattered data file representing the surveyed distribution of a parameter can be imported into the Argus Open
Numerical Environments Workplace.
To transform the conceptual model to a model of your specific problem domain all you have to do is to import your information files into the layers you've
defined. Argus ONE supports many file formats for importing your information, such as DXF, Argus ONE contour format, and scattered data. The information you import is stored as dynamic objects having both database and graphical
representations, enabling you to view and edit their "shape/location" as well as their values.
The following picture demonstrates how a contour map representing the spatial distribution of a parameter such as topography, bathymetry, concentration, or
initial head distributions can be imported into the Argus Open Numerical Environments Workplace.
Creating a conceptual model is performed by just clicking buttons in the Layers Dialog to create layers and naming the layers to reflect their contents. Each
layer can be assigned as many layer parameters as needed which serve as the layer's database fields. Thus if for instance your information file holds the Kx, Ky, Kz components of the distribution of a physical parameter, you
can create three layer parameters to hold each of the components.
Build a Conceptual Model of Your Problem Domain in Argus
The Argus Open Numerical Environments (Argus ONE) enable you to begin your work by creating a conceptual model of your problem domain. For each
of the domain characteristics, you define Information, Data or Maps Layers, which are databases containers and into which you then import your information. If your problem domain definition involves many parameters or is made
of many geological formations, each having many parameters defining it, you can create as many information layers as required to store all of the different information types.
By setting relations and links between information and data layers you create a data flow model which enables you to define new entities needed to describe your
problem domain. Thus you can create relations such as the thickness of a geological formation by subtracting its top and bottom topography maps. Each object you create or import into information layers is a GIS object having a
graphical representation and a data representation which you can edit on screen.
Dynamic Information Linking
Linking your data flow to numerical grids and meshes enables you to make your data available for your numerical
model. By storing your conceptual model and your information in linked layers and not directly on your grids and meshes, Argus ONE allows you to refine your meshes and grids while it automatically reassigns the data to them.
Argus ONE is the only product in the market that supports dynamic information linking.
