As stated earlier, the mesh you have is good. However, more important characteristic of the mesh is the height of the first cell. If it is too large as compared to the requirement of the models and the phenomena being studied, then you will have to refine it.

But it cannot solve the ununiform mesh size at some points of the circumference by refining the first cell, it always has that phenomenon.

I am afraid I do not understand what you mean by Phenomenon. As far as the mesh is concerned, if you want mesh to be similar to the one in the paper, you may have to refine it further. But at its current level, the mesh you have has a good quality. No comment could be given about since you have to check that in Fluent after running some iterations. If is less than 5, then it is good enough. If not, then refine it.

The laminar model is used in my simulation, the y+ cannot be checked. And mesh number is higher than that in the paper, so I think it can not solve the problem by refining it.

The reason your UDF does not compile is that either you do not have the compiler installed or Fluent cannot find it. You need to have either VS or VC+ or MS Build Tools with C++ compiler installed in your machine to compile a UDF

The UDF is directly downloaded from the fluent help, it is not edited by me, can you see what's wrong?(see attachment)

When I simulate the falling film flow, I use the lee model in-code, but it give the down errors, can you tell me why?


Error: CAR: invalid argument [1]: wrong type [not a pair]
Error Object: 0.

The code is good but not meant to be used for models other than Eulerian Wall Film Model.

I have used the Eulerian Wall Film Model.

When the fluent runs, it abruptly give the errors below, and I cannot run afterwards, what's the reason?
