Both initiated and uninitiated Sikhs are strictly prohibited from eating meat from animals slaughtered by halal method, known as Kutha meat, where the animal is killed by exsanguination (via throat-cutting). According to Eleanor Nesbitt, the general issue of vegetarianism versus non-vegetarianism is controversial within Sikhism, and contemporary Sikhs disagree. The
Volume of fluid method equations describing the motion of the flow have to be solved separately. The same applies for all other advection algorithms. The volume of fluid method is based on earlier Marker-and-cell (MAC) methods. First accounts of what is now known as VOF have been given by Noh & Woodward in 1976, where fraction function formula_1 (see below) appeared, although the first publication in a Journal was by Hirt and Nichols in 1981. Since VOF method surpassed MAC by lowering computer storage requirements, it quickly became popular. Early applications include Torrey et al. from Los Alamos, who created VOF codes for NASA
