New CullPyr
- Selects a portion of a pyramid, based on data values
- Uses data from
- base lattice, or
- top layer lattice, if present new
- Can select values inside or outside range
New ClipPyr
- Cuts pyramid with arbitrary oriented plane
- Can select pyramid elements either side of the plane,
or at the intersection with the plane
- Can select pyramid elements either side of the plane,
or at the intersection with the plane
- Preserves data at higher (non-base) levels new
Example
Reservoir data
- Simulation of oil transport through permeable medium
- Each cell has a permeability value
- CullPyr used to select cells inside or outside a range of
permeability values
- PyrToGeom creates geometry and colours it according to cell data
- DrawText creates caption which dynamically updates as range
changes
Lines of force
- Measurement of forces between spheres in an amorphous sphere pack
- Data stored as a pyramid
- sphere coords in base lattice
- forces in lattice at layer[0]
- CullPyr used to select lines inside or outside a range of force values
- PyrToGeom creates geometry and colours it according to line data
FE data (4)
- FE calculation in cylinder
- Calculates mass fraction in elements
- ClipPyr used to cut into object and reveal internal structure
- PyrToGeom creates geometry and colours it according to mass fraction values
