在木材应用中,了解温度在木材中的分布情况,掌握木材在受热时的温度场,才能有效地控制解冻,才能对干燥和防腐问题进行深入的研究,才能合理使用建筑围护材料。近年来,随着计算机应用和计算技术的发展,用数值方法求解木材中的热传导问题将成为有效、实用的方法。在许多种数值方法中,有限差分法和有限元法是目前较为成熟和用得普遍的方法。其中的有限元法是对古典近似计算的归纳和总结,它吸取了有限差
In timber applications, knowing the distribution of temperature in wood and knowing the temperature field when wood is heated can we effectively control the thawing in order to conduct an in-depth study on the drying and anti-corrosion problems so as to make rational use of building envelope materials. In recent years, with the development of computer application and computing technology, it is an effective and practical method to solve the heat conduction problem in wood by numerical method. Among many numerical methods, finite difference method and finite element method are the most mature and commonly used methods. The finite element method is the induction and conclusion of the classical approximation calculation, which draws a finite difference
