I have a rectangular channel of 200m x 25m x 2m dimension. The bottom of the channel has a hump of approximately 30 cm in height and extends over 30 m at the center. I am working on Dynamic mesh where the hump has to propagate over the channel. I have divided the channel horizontally at Z=1m. Now I want to construct a structured mesh but I fail every time, as I get some slightly tilted elements at the bottom. I tried so many methods, but not able to figure out the actual approach that would lead me to construct a perfect structured mesh.
Earlier I constructed a structured mesh in the same rectangular channel with the body divided into 3 parts (the hump being a separate part altogether, the right of the hump and the left) But I don't know what exactly I should do to get a structured mesh.
Under any circumstance, I am not getting a structured mesh. The mesh in the image is the default mesh generated without any method.
I would be really grateful if you could help me in this regard.
