Dear Researchers,
I have a question and I hope that someone can give me answer as soon as possible.
I am performing FSI of a large wind turbine Using monolithic approach. So, I receive from the structural solver deformations and rotations (vector of 3-deformations) and (Rotation vector with 3 components). due to the different coordinate systems in both fluid and structure solvers, coordinate transformations are needed. Deformations can be transformed by means of either Euler angles or sequence of direct transformations (no need for translations as they share the same origin).
The main question is: Is it also the same for the rotation vector? if no, please how can I do that transformation?
PS:
I receive the rotation vector and then normalizied it to transform it later to quaternion. Euler angles can be then calculated from that quaternion.
Best regards
Mohamed
Please also see "Acoustic fields and waves in solids"by Auld for the rotational transformation.
Thanks Ersin, I will have a look on it. by the way, I tried to do the transformation of the rotation to see weather it make sense or not. I found that it is the correct way to find the rotations around other coordinate system.
