1. interface之定義為何?
2. 有些case 的 ACE-Solver之BC項中,如果把邊界條件由wall改成interface,則該  case卻無法跑模擬過程(會出現以下之文字),請問是什麼原因?
Boundary  condition Type : Interface
  
   Found a boundary with type interface
  
         Expecting a Interface_type   
  
         No Interface_type of  :      
            1. Arbitrary Interfaces      
            2. MDICE                     
            3. Couple (MPI)               
         were found                       
  
   if this interface was supposed to be one of above mentioned
   three types,
   then please make sure the bcs are correctly specified in the CFD-GUI
   else make sure there are no bcs missing in the problem
            any easy way to do that is to run the DTF executable
            as follows :  DTF -tc modelname.DTF
   else the interface bcs in the DTF file are not matching
        this can be attributed to several problems
            1.  using different curves to create matching interfaces
            2.  using single precision output of data to DTF file   
                     use zi_node_hash utility to fix the DTF file
   endif

Interface是指两个分区之间的交接面，用于实现两区之间信息传递，不可能用Wall代替——如果你的交接面正好是壁面，则应采用薄壁条件

interface是两个block的交接面，也就是两个区的重合面。它是由软件自己认定的，而且不会出错。
如果出现你说的错误，那就是你其它的bc设置有问题。你把要算的物理问题再理解下，把所有的bc重新 检查应该可以找出错误
