walberla::pe_coupling::CurvedLinear< LatticeModel_T, FlagField_T > Class Template Reference

Detailed Description

template<typename LatticeModel_T, typename FlagField_T>
class walberla::pe_coupling::CurvedLinear< LatticeModel_T, FlagField_T >

Linear boundary handling for moving obstacles.

This boundary condition implements the CLI scheme from Ginzburg et al. - "Two-Relaxation-Time Lattice Boltzmann Scheme: About Parametrization, Velocity, Pressure and Mixed Boundary Conditions" (2008) References to equations and tables in the code documentation are contained in this paper.

It uses one additional cell in inverse direction of the boundary handling for a linear interpolation.

In case not enough cells are available, one fall back solution is available: If no additional cell is available, the scheme is replaced by the bounce back scheme (see SimpleBB.h).
