Introduction to FEM in LS-DYNA Using the LS PrePost Visualizer

Estimated Time: 1 hour to 1.5 hours

Instructions

1. Read Palmeri 2005 here - one of the original important papers on how FEM was developed and validated for ultrasound elasticity

2. Work through the tutorial below on how the different terms of FEM relate to one another

Below is a video of what you should see if you successfully complete the tutorial above and look at the infinitesimal Z strain in LS PrePost

Below is what you should see when you look at the Ndv Z displacement in LS PrePost after completing the tutorial above
