just a simple wave.

For example I just build a rectangle of 5 of width and 1 of height, with a wave equation ruling the model, then I let the zero flux condition on all boudaries but one on which I apply a source term sin(10t[1/s)] for example. Then I mesh, very thin, then I compute , and then I look. The first wave front looks great, but after few seconds, later wave fronts collapse, still keeping a smooth shape, and waiting fewer seconds leads me to observe a nice crash of computation, I can now see the triangles defining the shape, and the wave no more looks like a truncated sine, but more like a blurry noise.
What should I do to have a good wave?
Best.
