template<typename LatticeModel_T>
class walberla::lbm::PdfField< LatticeModel_T >
Specialized field class for PDF fields (fields containing multiple particle distribution functions per cell)
In addition to a generic GhostLayerField, each PdfField contains a lattice model which - among other things - determines how macroscopic values like density and velocity have to be calculated. For this purpose, a set of member functions exist that can be used to set single cells (or the whole field) to equilibrium or to evaluate the density and/or velocity for specific positions. If you happen to have an iterator to a PdfField, you should use the free functions located in "MacroscopicValueCalculation.h" - you do not have to convert your iterator into x-, y-, and z-coordinates! Also, particle distribution functions (i.e., the values stored in the field) can be accessed using stencil directions, e.g. "pdfField( x, y, z, stencil::NE )".
Note that the behavior is different for compressible and incompressible lattice models. In the compressible case, the behavior and formulas are as expected from common LBM literature and the density is taken as the 0-th order moment of the PDFs and this value is used. In order to make LBM quasi-incompressible, it was suggested, e.g. in Q. Zou, S. Hou, S. Chen, G.D. Doolen, J. Stat. Phys. 81(1–2), 35 (1995) X. He, L.S. Luo, J. Stat. Phys. 88(3–4), 927 (1997) that the density is implicitly assumed to have a constant value of 1 in many cases (e.g. in getVelocity()), and only the deviation from this value enters some of the formulas, like the equilibrium distribution functions. Additionally, the PDFs are normalized around 0 in the incompressible case to increase the numerical accuracy, i.e. only the deviation of the PDF values from their respective lattice weight is stored. As a result, manually summing of the PDF values will yield the density deviation in this case. But the getDensity() function reverts this normalization (by adding 1) and will yield the physical density. This normalization, however, usually doesn't affect the implementation of functions like LBM sweeps.
