Description

This model uses

• d3q27 cumulant collision kernel for hydrodynamics
• d3q7 cascaded collision kernel for heat
• Boussinesq approx to couple heat with hydrodynamics

BC

• periodic
• Dirichlet - Equilibrium scheme (1st order convergence)
• Dirichlet - Anti Bounce Back (2nd order convergence)
• Dirichlet - Interpolated Anti Bounce Back (2nd order convergence)

• Neumann like bc - impose heat flux

• WVelocity inlet

• EPressure Outlet
• Neumann Outlet
• Convective Outlet
