I need help and suggestions on my Basilisk code, as I am currently struggling with grid refinement issues.
I have attached one picture to show exactly where I need the help.
I have a solid half-cylinder where the drop falls and remains stationary (attached a picture). I used a no-slip boundary condition, and since the cylinder is solid, there is no penetration. However, the picture appears to show penetration, which is not the case. The problem originates from the grid refinement.
Please provide suggestions or insights.
I have provided my sample code in the attachment.
