    • Systems and methods for conducting thermal analysis in materials and devices having multiple thermal control zones (102) are provided. Modern apparatuses, such as manifolds (202), generally have several thermal devices (206) that introduce or remove heat at different rates from several different regions. Previous attempts to determine a thermal profile (116) required constant guessing and an unknown number of simulations to arrive at an acceptable result. Further, since the number of simulations required is not known from the onset of the operation, the duration is unknown, which is often unsatisfactory to manufacturing personnel. Disclosed embodiments include the use of FEA (106) to aid in designing and/or evaluating manifold (200) systems. In one embodiment, finite element analysis is conducted to determine the heat flux caused upon other control zone (102) by a thermal device (206) in a specified control zone (110).
    • 提供了具有多个热控制区(102)的材料和设备中进行热分析的系统和方法。 诸如歧管(202)的现代装置通常具有多个热装置(206),其以不同的速率从几个不同的区域引入或去除热量。 以前尝试确定热分布(116)需要不断的猜测和未知的模拟数量才能得到可接受的结果。 此外,由于从操作开始不知道所需的模拟数量,所以持续时间是未知的,这对于制造人员来说经常是不能令人满意的。 公开的实施例包括使用FEA(106)来辅助设计和/或评估歧管(200)系统。 在一个实施例中,进行有限元分析以确定由特定控制区(110)中的热装置(206)在其它控制区(102)上产生的热通量。
