mus_derQuanIncomp_module Module

This module provides the MUSUBI specific functions for calculating macroscopic quantities from the state variables for incompressible LBM models.\n Notice that only those quantities that related to density should have a formula which differs from normal LBM model.

The depending common interface between MUSUBI and ATELES is defined in the tem_derived_module. The functionality for accessing a variable from the state and evaluating a lua function are also provided in the tem_derived module.

Do not use get_Element or get_Point routines to update the state !

public subroutine applySrc_absorbLayerIncomp(fun, inState, outState, neigh, auxField, nPdfSize, iLevel, varSys, time, phyConvFac, derVarPos)

Update state with source variable "absorb_layer". absorb_layer is used to absorb the flow and gradually reduce the flow quantities like pressure and velocity to a fixed value for incompressible model. It is based on: Xu, H., & Sagaut, P. (2013). Analysis of the absorbing layers for the weakly-compressible lattice Boltzmann methods. Journal of Computational Physics, 245(x), 14–42.
