The efficient computational contact and flow model from funding period one will be extended during the second funding period. The mechanical modeling will additionally consider the flexibility of the mould, deformation dependent surface tension, frictional contact and transient inertia effects of the melt flow. Furthermore, heat conduction, heat transfer and the resulting solidification will be integrated into the model. New boundary-element methods will be developed in order to provide an efficient computational description of the thermo-mechanical behavior of the melt flow. The extended model will then be used to simulate and study the applications of other subprojects (such as injection molding and soldering).

第一个供资期的高效计算接触和流动模型将在第二个供资期内得到推广。机械建模还将考虑模具的柔性、变形相关的表面张力、摩擦接触和熔体流动的瞬时惯性效应。此外，热传导，热传递和由此产生的固化将被集成到模型中。新的边界元方法将被开发，以提供一个有效的计算描述的熔体流动的热机械行为。扩展后的模型将用于模拟和研究其他子项目（如注塑和焊接）的应用。
