Hi I am doing simulation with a curved wall that has a velocity and I know that the velocity components have to be tangential.

But because for this particular geometry I don't have any information on it I just chose a velocity vector that suited most of the wall, and my idea to get around it (just for this case) was to increase the tangential vector tolerance in expert parameters however although I have chosen 35 degrees (which is higher than the max difference) it still comes up with the error

Is there something else that has to be done? or is there a limit on this tolerance?
