pt = THREAD_SUB_THREADS(mixture_thread); mixture_thread是一个指向mixture级别的thread指针,其可以代表一个网格thread或一个网格面thread。当使用包含thread变量参数的DEFINE宏(如DEFINE_PROFILE),且该UDF加载到mixture相时,其被Fluent求解器自动传递给UDF。若mixture thread指针没有显式地传递UDF,则需要使用其他方法(...

在上面的例子中,要事先获得超级域的指针。如前文所述,某些函数勾在超级域上,求解器就会自动传递超级域指针到UDF。而某些函数则不能显式地得到超级域的指针,则需要用宏Get_Domain(1)来获取。 3 已知超级线的指针,则可以使用THREAD_SUB_THREAD宏求的其子线的指针。
for the ith phase, where i is the phase_domain_index. For example, C_VOF(c,pt[i]) can be used to return the volume fraction of the ith phase fluid at cell c. The pointer pt[i] can also be retrieved using THREAD_SUB_THREAD, discussed in Section 6.5.4, using i as an argument....
