The goal of A05 is a simulation environment of the L-DED process that combines different scale levels to holistically describe a HyPo-component during and after the manufacturing process. A micro level thermo-fluid structure simulation specifies the effective heat input and the shape of the applied layer. A feature level model calculates the thermo-induced residual stresses. On component level, large HyPo-components are efficiently described by spatially and temporally variable properties, e.g. shape, residual stresses, temperature and porosity.

A05的目标是L-DED过程的模拟环境，该环境结合不同的尺度水平，以在制造过程期间和之后全面描述HyPo组件。微观层次的热流体结构模拟指定的有效热输入和应用层的形状。特征级模型计算热致残余应力。在组件级别上，大HyPo组件有效地描述了空间和时间可变的属性，例如形状，残余应力，温度和孔隙率。
