A novel volume of fluid (VOF) based approach is proposed to simulate the transient shape change of deposit front during electrodeposition considering secondary current distribution. Transport phenomena such as electrolyte potential, electric current density, and fluid flow of electrolyte are computed. The presented algorithm comprises computation of the exact VOF interface area as well as proposed modeling equations to accurately handle transport phenomena within the deposit. Based on the modeling results, it is essential to minimize the overshoot of electric current near the singularity between the cathode and insulator in the beginning stages of electrodeposition to achieve a relatively uniform thickness of the deposit layer in electroforming process. The results are validated against existing mathematical solutions.

提出了一种基于新体积流体（VOF）的方法来模拟考虑二次电流分布的电沉积过程中沉积前沿的瞬态形状变化。计算诸如电解质电势，电流密度和电解质的流体流动的传输现象。提出的算法包括精确的VOF界面面积的计算以及提出的建模方程，以准确处理矿床内的传输现象。根据建模结果，必须在电沉积的开始阶段将阴极和绝缘体之间奇异点附近的电流过冲最小化，以在电铸过程中获得相对均匀的沉积层厚度。根据现有的数学解验证了结果。
