Hi _1 billy This issue can occur due to poor mesh quality/incorrect setup. Have you checked mesh quality? Make sure min Orthogonal quality 0.1 and Max Skewness < 0.98. If mesh quality is good, please check the setup to see if you are using the appropriate model and boundary conditions for your simulation.
You can find more information below.
