Hi,
I am very new to CFD and I am trying to just make a domain and generate waves in this domain. So when I try to make a mesh, it looks kind of weird. Why does spots with higher density of cells occur at random places, as seen in attached picture. I guess there's a simple setting or something I haven't checked. Sorry for a very newbie question. |

Can you check the surface growth rate? ref below Regards, Sam0508

Hmm before going to the volume mesh, can you show us the surface mesh /intial surface of the domain? (make sure the mesh if on to be seen)
I suspect there is something not righ even with the surface mesh / initial surface |

You can try to check these values,
* Surface curvature (reduce the default value - this put more less points around the circle) * Surface size (increase the cell size - increase the minimum triangle size) and can you show geometry screen? i think geometry have some circular feature edges on the extensive areas like a point, and i think some close proximity detail in extensive meshed line.. |
