WORKSHOP VIII: USING RIGID BODIES
The implementation of rigid bodies open doors to making your models run
faster and allows you to focus on what is important and avoid getting
distracted. For complex system level models, the use of rigid bodies is
invaluable and if desired can always be switched later on to deformable.
What You Will Learn
• How Rigid Bodies work within a simulation and how easy it is to switch to
deformable to gather deformation and stress information.
• Defining a fixed movement (i.e., punch movement) as a load case.
• Getting more familiar with the LSPP Interface for making model updates.
Student Led Workshop I: Switching Rigid Bodies to Deformable Bodies
The pendulum model starts out rigid and then is switched to deformable at the
last moment prior to impact. See Class Reference Notes / LSTC General
Examples Manual and Examples / EXAMPLES / DEFORMABLE_TO_RIGID.
This example provides insight in how to do
Restarts (See Class Reference Notes / Keyword
Manuals / LS-DYNA_manual_Vol_I_R7.0.pdf /
Section RESTART INPUT DATA). Two files are
provided that covers the complete run in the
directory noted above. Run the regular model
and then perform a restart. A small movie file is
provided to show how the process works (see
Workshops / Student Led Workshops.
