Hello, i have run the wingmotion2D tutorial of Openfoam V10, through which ive been trying to learn dynamicmeshdict. The tutorial consists something called orientation which i got to know is a rotation tensor.

centreOfMass (0.4974612746 -0.01671895744 0.125);
momentOfInertia (1.958864357 3.920839234 2.057121362);
orientation
(
0.9953705935 0.09611129781 0
-0.09611129781 0.9953705935 0
0 0 1
);
angularMomentum (0 0 -2);
g (0 -9.81 0);
rho rhoInf;

i tried changing the values in the orientation matrix but it always shows an error: the given orientation is not a rotation tensor, and some equation saying mag(orientation) - sqrt(3) = some value.
It would help me lot if i can learn how to change the orientation correctly and what is the sqrt(3), im assuming its because of rotation about 3axes (i might be wrong).
i changed the values based on a rotation tensor matrix equation i found somewhere which included the angle of rotation about each axis, yet the error continues. i would really appreciate the help to know how to use the orientation in dynamicmeshdict.

Thank you,
Regards
Rohan

So, i somehow resolved the error, but now it seems like even if i change the angle in orientation the mesh isnt rotating about that angle but only until the default tutorial setup, i have also tested the force results before and after changing orientation, but they seem to not change at all.
would really appreciate the help.
Thank you
