ReadPhoenics

• PHOENICS = cfd solver
• Handles grids with:
  • cartesian
  • cylindrical
  • body-fitted coordinates
• Reads .phi + (if necessary) .xyz files
• Interpolates data to cell corners
• Outputs multi-channel lattice

VectorDisplay

• Creates lines & arrows from vector data
• Can colour vectors according to
  • magnitude (total/horizontal/vertical)
  • vertical position
  • some other scalar variable
• Control over line thickness
• Toggle display of zero-length vectors
• Update of VectorDisp - NCSA PATHFINDER module

Particle advection modules

• Visualisation of vector data
• Generate particles in subvolume
• Advects particles to create streamlines
• Uses solver (Runge-Kutta, nag_ode_ivp_rk) from NAG C library
• Solver determines integration step
• Choice of subvolume location & size
• Choice of interpolation methods
• Variety of output options

NAGAdvectSimple

• Particles traced over fixed time interval
• "String of beads" representation
• Separation of particles on trace related to velocity
• Particle traces distinguished by colour
• See spiralpath demo map in Release 3.0

NAGAdvectAnimate

• More options for display
• Can colour particles & path using
  • velocity
  • time
  • some other scalar variable
• Supports animation of particles & path
• See flowpath demo map in Release 3.0
