请教在自开发AMR求解器中应用cyclic边界条件报错

luca

各位前辈，我在自适应（AMR）求解器中，对左侧点火端开口，前后面设置为cyclic周期性边界条件，其他面为壁面的算例进行计算时，出现如下报错：

模型如下

周期性边界：

我的Boundary文件是这样的:

boundary
(
     outlet
     {
        type patch;
        faces  
        (
           (0 4 7 3)
        );
      }
     

     endwall
     { 
        type patch;
        faces  
        (
           (1 2 6 5)
	   
        );
      }

     upperwall
     { 
        type wall;
        faces  
        (
           (4 5 6 7)
	   
        );       
      }

     lowerwall
     { 
        type wall;
        faces  
        (
           (0 3 2 1)
	   
        );       
      }

     frontwall
     { 
        type cyclic;  
        faces  
        (
           (0 1 5 4)
        );
        neighbourPatch backwall;
     }

     backwall
     { 
        type cyclic;        
        faces  
        (
           (6 2 3 7)
        );
     neighbourPatch frontwall;
      }

); 

                                     
mergePatchPairs                      
(   
	                            
);

我目前怀疑是因为网格不断加密后，由于数据的传输出现问题导致，有没有遇到过类似问题可以一起讨论一下的。

单核是可以运行的，但是一旦并行运算就会报错。

田畔的风

Cyclic似乎只适合几何拓扑一致的网格边界吧，你这种情况用cyclicAMI边界可能会好一些。

luca

@田畔的风您好，请问您有设置cyclicAMI的相关案例么，能参考下吗？

@luca 在请教在自开发AMR求解器中应用cyclic边界条件报错中说：

我在使用并行计算时也遇见了相同的问题，题主解决了吗？
