I now have wave propagation!
I have initiated a 'hit' constraint on the middle bottom nodes. The wave will now start to propagate into the medium.
And the last shot.
Note the leading 'fuzz' from the main pulse. This is most likely an instability propagating directly per time step. I used to get this all the time. The solution is to 'shape' the input curve into a cosine wavelet (smooth bump!), and to decrease the time interval. All in all, I am amazed at how quickly this runs, and I can specify 2 processors if I want to!
I was working on gmsh which is a better modeler. I intend to eventually model soil on rock, a structure on rock, and a structure on soil. Based on my previous modeling, it will show how the 'old guys' have it all wrong when they deal with structural resonance, mainly because of those deep horrible assumptions.
All in all, I'm very happy, and I'm glad I forced myself into this.
