近三十年来，聚合物的激光烧蚀一直是广泛研究的课题。研究结果表明，在三纳秒频率Nd:YAG激光烧蚀聚酰亚胺过程中，热效应起着重要作用。尽管进行了研究，但这些过程的影响尚未得到令人满意的澄清。热效应、光化学和其他现象仍然存在，因此激光烧蚀的热建模是一个非常专业的问题。本文的研究涉及热模型中的特殊条件，这些条件与更常见的条件有很大的不同。虽然有许多优秀的热建模软件可用，主要是在电子技术领域，但这些软件不适合或准备处理特殊条件，例如从正在研究的领域中去除材料，这是最重要的领域之一。因此，我们决定开发一种特殊的热建模工具。本文给出了模型设计的几个方面，这些方面定义了开发过程。
Laser ablation of polymers has been the subject of extensive studies for nearly three decades. Results of these investigations have shown that thermal effects play an important role during frequency tripled nanosecond Nd:YAG laser ablation of polyimide. Despite of the studies, effect of these processes has not been satisfactorily clarified. Thermal effects, photochemical and other phenomena still exist and so the thermal modelling of laser ablation is a very specialised problem. The investigation in this paper deals with special conditions in thermal models, which highly differ from more common conditions. Although there are numerous excellent thermal modelling software available, mainly in the field of electronics technology, these are not suitable or ready for handling special conditions, for example the removing of material from the domain under investigation, which is one of the most important areas. Hence we decided to develop a special thermal modelling tool. The model designing aspects which define the development process are presented in this paper.
