hi every one
i done mesh for spillway as shown follow,i used body sizine with element size=0.5 and inflation 2 faces shown (i only want extract results in spillway) with first layer height =0.1, maximum layer=60 unfortunately my result have high error with experimental data, I've analyzed model for 4 days , finally today finished and i countered with high error in compared results. could any one please give me advise. thanks in advance |

that looks like a poor mesh, what is the mesh quality, see the orthogonal quality n post that, use inflation on all walls, just to cover your boundary layer not like the one you have ATM

this is not orthogonal quality, go to statistics it should be there, read some meshing tutorials by Ansys, google them
