Hello,

In the frame of a project i am working on, i am trying to simulate in 2D the rotation of the legs during swimming. I am using a very simple model composed of 2 rectangular beams :
- one fixed to simulate the upper part of the body
- one rotating between (-60° ; 60° ) at the tip of the first to simulate the legs

From the research i've been doing, i understood that i should use User Defined Function to make the lower part rotating.
Is there a more simple solution ? If not, could someone explain me how to write
the kind of UDF i need.

Thank you
