Hello everyone,


I am currently working for a channel flow project. I am wondering about the velocity field plot in the midplane of the fluid. It looks very pixelated. I always thought that Paraview is interpolating the values and a very smooth velocity distribution will be shown. In previous different projects I never had this strange behaviour. Could it be that the mesh is too coarse and a smooth interpolation is not possible or what could cause to this problem?



Many thanks for your help and best regards,
Daniel
