The built-in infinite elements do not eliminate all the reflections. Can PML be implemented in Abaqus time domain explicit solver? Thanks!
It seems like leapfrog is defined for the 2nd order PDE wave equation. For a 1st order formulation like the velocity-stress formulation, is there a way to use the leapfrog integration? The reason...

Hi, I am doing forward wave simulation in 3D space. One of the problems is that since the Poisson's ratio is close to 0.5, the compression wave speed is much faster than that of the shear wave....
