一种改进的流体体积法是在一个固定的网格，有限体积模型模拟传输现象，凝固，和电磁学。VOF模型与已发表的结果吻合良好，完整的模型被用来研究电渣重熔过程中的工艺变化，在电渣重熔过程中，液态金属从浸入电阻渣中的自耗电极熔化。熔融金属通过漂浮在液态金属池上的渣帽下沉，同时渣皮冻结到模具上。在这里，VOF跟踪渣皮的形成及其对不同电流水平和锭直径的熔化速率的影响。
A modified volume-of-fluid method is implemented in a fixed-grid, finite-volume model simulating transport phenomena, solidification, and electromagnetics. The VOF model agrees well with published results, and the complete model is used to investigate process variations in the electroslag remelting process, in which liquid metal is melted from a consumable electrode immersed in an electrically resistive slag. The molten metal sinks through the slag cap floating on the liquid metal pool while a slag skin freezes to the mold. Here a VOF tracks slag skin formation and its effects on melt rate with different current levels and ingot diameters.
