Moving wall boundary condition-Both rotational and translational velocities

      Hello, 

      I would like to ask whether is possible to include rotational and translational velocity in the boundary conditions of a wall? 

      It seems I can only choose one of them. 

      Kind regards,

      Hi Thodorisdm,

      I think this can be done by the 'Components' option in the 'Motion' section. Choose the Components option and this can be achieved using a profile or a user-defined function for the X-Velocity, Y-Velocity, and/or Z-Velocity of the wall.

      Hello, 

      Thank you for the reply. 

      Just for clarification : By user defined function do you mean expression because I cannot insert a UDF in the components section. 

      Kind regards,
