PTM particle trace

Particle Module

  • Visualize particle/path data
  • Supports PTM model which computes particle positions through time based upon hydrodynamics and wave effects

More Info...

Models

  • SMS is a graphical interface that supports many numeric models
  • The models were developed by government or private entities
  • Hydrodynamic models compute water surface elevations and velocities (ADCIRC, SRH-2D, TUFLOW, etc.)
  • Wave models compute wave characteristics (BOUSS2D, CGWAVE, etc.)
  • GenCade is a shoreline model that predicts how the coastline will move based upon long term wave information
  • PTM tracks particle positions through time based upon hydrodynamics and wave effects

Visualization Tools

3D view of color filled contours

Contours

  • Visualize scalar datasets
  • Linear, color filled or both at the same time
  • Variable level of transparency
  • Full control of ranges and colors
  • Precision control for labels and legends

More Info...

Vectors display

Vectors

  • Visualize vector datasets as arrows
  • Constant size or vary by magnitude
  • Show just a range of magnitudes

Plots

  • 2D plots to visualize results and compare to measured values
  • Profile plots view scalar data along an arc
  • Time series plots view scalar, vector, or flux (flow rate) data at a point or across an arc
  • Several kinds of plots can be used to compare model results with measured data

More Info...

Wave functional surface

Functional Surfaces

  • Surface with elevation based upon scalar dataset values
  • Very useful for wave models and models with large change in water surface elevation
  • Elevations can be exaggerated to better visualize dataset variations
  • Surfaces can have a solid color or use color filled contours

Animations

  • Several types of AVI animations (film loops) can be generated by SMS
  • Transient data animation shows model changes through time (contours, vectors, etc.)
  • Flow trace uses vector data to generate flow paths through the geometry
  • Drogue plots use user specified starting locations and show how the particles would flow through a vector field
  • Multiple view animations show the data while transitioning between different views
  • Plot window animations show plots changing through time

2D Mesh Polygon Properties dialog

Meshing Options

  • Generating a quality finite element mesh is central to using many SMS models
  • Conceptual models make generating meshes easier
  • Polygons can use a variety of meshing options to generate triangular or quadrilateral elements
  • Polygons can be assigned bathymetry and material information that will be transferred with the mesh
  • Constant paving density and Scalar paving density generates elements with sizes based upon a size dataset allowing for smooth transitions and a large range of element sizes and is particularly useful for coastal and wave models.
    • For the constant option, the element target size is specified for each polygon.
    • For the spatially varying (scalar paving) option, the target element size is based upon a size dataset on a TIN allowing for smooth transitions and a large range of element sizes.
  • Datasets for scalar paving density can be user defined or generated using the Data Calculator, the Dataset Toolbox, or LTEA (linear truncation error analysis) (ADCIRC)
