I have been trying to mesh the channel with a pile at the center, but I am not satisfied with the mesh that is being produced. I have used several Sphere of Influence with 0.2 m element size and an “Automatic method”. The average size of the elements is between 0.3 - 0.5 m. I have also used 2 inflation layers (one around the pile and the other from the bottom surface) and merge them. The mesh gives me some weird looking elements on the side walls (image attached). The number of nodes and elements is quite high (1133359 and 5038577 respectively). The skewness of the elements is found to be 0.71 [Good] although I had changed the target skewness to 0.70 and the orthogonal quality is found to be 0.19 [Acceptable]. I have attached images of the mesh and if you have any suggestions to make it better, it would be really great!
Please help me
