Model your own flexible fiber
Given all the models available, you can pick the model and calibrate its coefficients so that
your fiber mimics the behavior of your particular material.
In Video 7 below, you can see how fibers with different joint stiffnesses behave differently when
impacting the surface while driven by the airflow.
Hay Tedder Performance
In the case study shown in Video 8 below, the goal was to model a hay tedder and compare
different operating conditions to ensure proper material handling. Flexible fibers were used to
model the hay, and the multi-GPU capability allowed the customer to simulate a large number
of fibers.
