Distribution of flow velocity is wrong


I created a cfd model of cylindrical geometry based on Aneurysm example and executed training.
However the result was not as I expected. The distribution of flow velocity is wrong. The velocity magnitude in outlet is greater than that in inlet about for 30%.

My env. is SimNet 21.06.

I uploaded the model package.
Could you let me know what is wrong?
