About the job
I simulated with another tools the motion of a person doing a tennis serve. I have represented the skeleton of a human with 75 points and I have coordinates of those point over time (see GIF for a python representation).
I added those joints as Motion Bodies in a Simcenter Motion simulation and I replicated the motion without any problem. The model runs and everything moves as supposed ( I attach sc3d files of the model). Apart from that, I also added a CAD model of a tennis racket and I created the string pattern. This is at the moment just there and not part of the simulation.
So the task are:
1) Add "beams" in between the joints just as aesthetics during the simulation. While, run I want to see something connecting the joints, not just ball, representing the body. It does not have to be structural or flexible bodies but it needs to be notizable. As you will see upon opening the model, I created already cilinder in between all joints in case it helps and you want to create sphere-sphere joints in between , or tie contacts , or flexible bodies. To me it does not matter, I just want something solid that shows in the post-processing.
2) Connect the racket model to Joint 1, Joint 2, Joint 3. As you will see upon the model the racket is positioned moreor less in the Joint that represent the wrist of a person, I need the racket to follow the movement of Joint 1-3 more or less.
3) The hard part. I want the racket and strings as a flexible body. Mesh the racket frame a...

3) The hard part. I want the racket and strings as a flexible body. Mesh the racket frame and the strings, connect the strings to the frame and output stress,straims, RF...etc from them.
4) Create a ball (sphere) that is thrown at the begining of the simulation from the hand and impact the racket as a normal serve in the high point of the movement.
I attach the Simcenter motion files (including the input file), a GIF with the movement and another mp4 of the implementation on Simcenter Motion. As I explained before, that movement should not be modifie, it is implemented in drivers in the joints.
If someone is interested and has more question, please let me know. I would also appreciate not sharing the model or GIFs as this is obtain by myself with a motion capture suit.
