Hi,

I am trying to use the overset pimplefoam solver to simulate an aileron deflection + full body roll motion. In dynamicMeshDict:

left
    {
        cellZone left_flap_zone;

        // Solve displacement on top of solid-body rotation
        solver solidBody;

		solidBodyCoeffs
        {
            
			solidBodyMotionFunction  multiMotion;
            multiMotionCoeffs
            {
                rotation_1
				{
                    solidBodyMotionFunction  rotatingMotion;
					rotatingMotionCoeffs
					{
						origin (0.82844 0.068725 1.612);
						axis (0.30561883566790207600295853841501 0.05308097543117203395473586094744 0.95067320217426512707324472297049);
						omega       2.9;//0.269; // rad/s, 1rad/s=9.5rpm
					}
                }
				rotation_2
				{
                    solidBodyMotionFunction  rotatingMotion;
					rotatingMotionCoeffs
					{
						origin (0.1 0 0);
						axis (1 0 0);
						omega       2; // rad/s, 1rad/s=9.5rpm
					}
                }

			}
		}

	}

However, I realise that when combining both rotations, the axis and center of rotation changes for the aileron when the body, together with the aileron, does a roll motion.

So if I need to implement a aileron deflection together with roll, how can I achieve it? Must I write a routine? I hope not ;-)

Thanks.

Hi!


Can you, please, upload a minimal working example of this?
