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
Examples
Mixing vessel with tangential feed
Eccentric drilling annulus
Airflow around a moving van
Circulation in double glazing
