Erratic high stresses in structural simulation

      I am working on a model for wave propagation. I have modeled 3D steel bar (6 in x 0.5 in x1in) with a point impulse load at the outer edge for explicit analysis.The mesh parameters are also acceptable with mesh size of 0.01 inch, max aspect ratio of 1.6 and min Jacobian of 0.9. I have used fully integrated elements as I need data on all the frequency bandwidth. The simulation runs fine but I am getting erratic high stresses and strains ( range of 10e27) in posterior part of model ( at length more than 4 inches). Could anyone please explain the solution for this problem?
