I have tried several times, including the past questions that are solved. I could decrease the error significantly, but I still can not solve this particular problem. Here is the code,

I do not understand why does the 76 th line gives me an error. Anybody knows why?

Hi,

The error is because there is no hex block where the vertices 13, 6, 5 and 12 are ALL present. In order to define a set of vertices as a face, they must all be present in the same block.

Hope this helps.
