Hi, I'm using FLUENT v 13.
it's a 3D case with a model of a cylinder. the motion of the cylinder is in xy plane. I use smoothing and remeshing strategy. it works well in 2d, but when I change to 3D, after some iterations, the skewness of the first layer mesh outside the rigid moving body get very high, and negative volume appear. Can anybody help me? Thanks a lot |
