How to set wobbling axis for sphere in fluent
 
hello everybody,

Just want to ask, can we set the wobbling axis movement of sphere in fluent and how to do that. Do I need to use the sliding mesh method (but the axis in this features could not move with time, if i'm not mistake) or do I need to create code for UDF to define the movement (is there any available source code for this case..uhuh). Anyone help me pleasee... :(

For clear visualization, here is how the motion of sphere that I'm going to simulate in fluent....https://www.youtube.com/watch?v=CUZOXczMfMo

Hi heatdrive,
Hope you are fine. Please have you learned how to create new axis in fluent since now I have the same problem and I need to create new axis to rotate the heart valve.
Best regards,
please if you have any tutorial or any thing related with this that will be appreciate.
Tanks in advance,
Mohammed
