Dear all:
Recently, I met a agonizing problem which is about mesh difference between 14.5 Version and 15.0 version in Ansys meshing. My question is below:
In Ansys meshing 14.5 version, I split body with a face (figuer 1)which I want to simulate as wall and used default CFD methods, the detail mesh in figure 2
But in Ansys meshing 15.0 version, I performed same operations with same case, the face simulated as wall was missing in figure 3, I do not know what make such a difference, can anyone met a same problems and tell me what I can do to resolve it?
