maxCellsPerParticle = maximum number of cells covered by a particle (search will fail when more than maxCellsPerParticle cells are covered by the particle)

Description

The IBSuperquadric voidfraction model is supposed to be used when a superquadric particle (or its representation) is bigger than a CFD cell. The voidfraction field is set in those cells whose centres are inside the particle. The model is specifically designed for cfdemSolverIB and other IB solvers and creates a smooth transition of the voidfraction at the particle surface. Cells which are only partially covered by the particle are marked by voidfraction values between 0 and 1, respectively.

Code of this sub-model contributed by Alexander Podlozhnyuk, DCS Computing GmbH.

Note

This model requires the particle shape type to be set to superquadric AND that the force models use this shape type.

Restrictions

Only for superquadric particles.
