obstacles aren't obstacle-ing

i’m basically throwing a ball of water at a wall, but most of the fluid passes right through the wall. the wall is set as an obstacle and configured with the defaults. the fluid is also all default.
EDIT: solved by increasing the thickness of my wall through extrusion.
