good day to all.
i need your help.
i have a rigid body(high speed planing hull) and also want to simulate circle maneuver with mesh motion.
at first i dont define any external force on rigid body. but the rigid body moves toward x coordinate (move forward)..
all of boundaries are opening and domain and its mesh move with rigid body(mesh motion).
gravity =y coordinate
x direction is parallel to the length of the rigid body.
why we have motion in x direction for rigid body when we haven't any external force or inlet boundary.?
