本文的目的是阐明如何以及何时3D模拟优于2D模拟，以预测通过塑料注射成型的纳米腔的复制高度。模拟是必要的，因为根据几何和注射条件，并非所有的腔都被复制。在两种情况下，3D模拟优于2D模拟：（i）当通过平行于模拟域的壁的热传递不可忽略时，以及（ii）当聚合物最终形状相关时。这项工作解释了当2D模拟像更常见的文献中发现的是不足以获得可靠的结果，以及如何通过3D模拟获得这样的结果。
The purpose of this paper is to shed light on how and when 3D simulations are preferable over 2D simulations in order to predict the replicated height of nanocavities via plastic injection moulding. Simulations are necessary since not all the cavity is copied depending on geometrical and injection conditions. A 3D simulation is preferable over a 2D simulation in two cases: (i) when the heat transfer through the walls parallel to the simulated domain is not negligible and (ii) when the polymer final shape is relevant. This work explains when 2D simulations like the more commonly found in the literature are not enough to obtain reliable results and how to obtain such results by means of a 3D simulation.
