velocity as a function of space boundary condition-LS Dyna

Wasif · October 27

Hi,

I would like to apply Velocity as a function of space on of the faces/edges of my model. In ANSYS LS-Dyna Extension, the only Option is to give Velocity as a function of time in Tabular form.

How can i proceed?

Use *BOUNDARY_PRESCRIBED_MOTION with VAD=0, and if LCID refers to *DEFINE_FUNCTION, the function has four arguments: time and 𝑥, 𝑦 and 𝑧 coordinates of the node.
