我们介绍了不同的近似的热力学性质的对流系统类似地球的地幔。包括真实的几何形状，流变学和断层，以确保我们看到的变化在动态，自缓冲环境中是稳健的。我们在系统中发现两个层次的响应。首先，一些近似导致模拟中非常不同的流动模式。第二，其他几组近似导致类似的流动模式，但流动的时间历程随所用公式的不同而显著不同。最后，我们注意到，只需要对现有的代码进行微小的修改，就可以集成一个复杂的热力学模型。
We introduce varying approximations to the thermodynamic properties of a convecting system similar to Earth's mantle. A realistic geometry, rheology and faults are included to insure that the variations we see are robust in a dynamic, self‐buffering environment. We find two levels of response in the system. First, some approximations lead to very different patterns of flow in the simulations. Second, other sets of approximations lead to similar patterns of flow, but the time history of the flow varies significantly with the formulation used. Last, we note that only minor changes to an existing code would be needed to integrate a complex thermodynamic model.
