热接触设置

在interaction模块下！如果两固体之间接触，但未完全贴合，需要定义接触热阻；如果完全贴合，直接“tie”，不需要额外的定义，通过节点直接传递温度！
manual里面的描述：
A tie constraint ties two separate surfaces together so that there is no relative motion between them. This type of constraint allows you to fuse together two regions even though the meshes created on the surfaces of the regions may be dissimilar. You can define a tie constraint between edges of a wire or between faces of a solid or shell.
简单得理解就是在无运动联系的两个面可以使用tie使两实体网格相互连接。
没有试过，看到帖子我又仔细查了一下manual，有所发现，等我试过再上图。
哈哈！

最近也在学习热分析，按照我的理解是在interaction模块设置接触contact，设置thermal里面thermal conductance 设置接触面的热传导系数！但是里面涉及到 clearance-dependency 与pressure-dependency data，在数据设置上似乎没有摸出头绪。
CAE manual里面介绍也只是比较笼统，如下：

To specifythermal conductance:

ClearanceDependency（应该是一个关于间隙与系数的线性关系）

Inthe data table, define thermal conductance as a function of gap clearance.

Thetabular data must start at zero clearance (closed gap) and define thermalconductance as clearance increases. You must provide at least two pairs ofpoints. The value of thermal conductance drops to zero immediately after thelast data point, so there is no conductance when the clearance is greater thanthe value corresponding to the last data point. If conductance is not alsodefined as a function of contact pressure, it will remain constant at the zeroclearance value for all pressures.

Pressure Dependency

Inthe data table, define thermal conductance as a function of contact pressure atthe interface.

Thetabular data must start at zero contact pressure (or, in the case of contactthat can support a tensile force, the data point with the most negativepressure) and define thermal conductance as pressure increases. The value ofthermal conductance remains constant for contact pressures outside of theinterval defined by the data points. If conductance is not also defined as afunction of clearance, it is zero for all positive values of clearance anddiscontinuous at zero clearance.

纯属自己的理解，希望各位大神能指出错误！

若谁有相关的算例希望能拿出来共享下，谢谢！
