    Hi all, I am modeling the wave propagation in tissue. I set the tissue to be hyperelastic and introduced an artificial viscosity with the abaqus default values (linear 0.06, quadratic 1.2), However, I found these default settings changed my wave too much, so I am trying to adjust those values...

    3D geometry creation - double layered sphere in a cube

    Hi, I am quite new to Abaqus, now I have to create a geometry of a sphere with two layers inside a cube. What I did was creating a extrusion of cube, then created three orthogonal datum planes inside the cube and partitioned circles on them. However, it seems it is not the real volume inside...
