Wave propagation analysis

Still moving along. Got sidetracked with model generation, which was a big waste of time. Figured out how to animate an impact.

This is the max displacement vector. You can see the fundamental starting to come in, which will be the block pulsing up and down. I'm always fascinated to watch the transients become the fundamentals. All of traditional seismic analysis skips the transients.

ps. 1st few frames are at the last.

I'm impressed! Why don't you show us more?

I put them on as soon as I figure them out! I spent hours trying to get quad elements out of gmsh! For now I'm sticking to the built-in capabilities of Impact, and trying to figure out how to properly sort the output pictures, so they don't muck up when I make them into a movie.
