SmoothViz

SmoothViz is a tool for visualization and exploration of Smoothed Particle Hydrodynamics data. Intuitive graphical interface helps to call efficient algorithms to operate scalar fields (transfer function manipulation, isosurfaces extraction, projection view, etc.), to represent vector fields (e.g., streamlines), and time varying datasets (navigation in time, extraction of pathlines).

Hamiltonian Particle-Mesh method (HPM) was  successfully applied for numerical solution of (Rotating) Shallow Water Equations, which are extensively used to simulate geophysical processes. HPM is a hybrid numerical method. It has a natural adaptivity like most particle methods. At the same time, it incorporates the procedure of artificial smoothing of the depth field over a regular grid into the classical Lagrangian formalism. This smoothing reduces the numerical noise and can be viewed as an efficient implementation of Smoothed Particle Hydrodynamics for globally supported basis functions. HPMviz is a tool which serves to perform simulations using HPM method, investigate the behavior of the solution with respect to the key parameters (number of particles, grid resolution, smoothing scales, type of kernel functions, etc.), and visualize the results.
