SubscriberHello, any help or tips are appreciated!
I am a uni student trying to simulate the rotation of a rectangular body along the z axis whilst another remains stationary (similar to a knee joint when someone stands/sits). I've been told to look at dynamic meshing and creating a UDF however everything im finding is confusing and doesnt explain anything very well.
Just looking for a clear guide or some helpful pointers into the right direction.
thanks

Ansys EmployeeHi,
I suggest to refer fluent user's guide for dynamic mesh: 11.6. Using Dynamic Meshes (ansys.com)
If you are not able to access the link, please refer to this forum discussion: https://forum.ansys.com/forums/topic/using-help-with-links/#latest
Thank you

SubscriberHi,
thank you for your reply. Finding the guides useful but not specific, as in, i just dont know what everything means!
Is there some things i should keep in mind when creating these zones?
i.e enclosures round the components? internal meshes? booleans to subtract the component?
many thanks

Ansys EmployeeHi,
You can refer to dynamic mesh- Smoothing, remeshing. You can apply UDF for movement to the rotating part.
For UDF you can refer to the macro DEFINE_CG_MOTION
You can refer to fluent customization manual for more details regarding macro DEFINE_CG_MOTION
Thank you.
