  • Fast Multipole Method (FMM)

    Solve large-scale 3D elastoplastic analysis with the Fast Multipole Method (FMM). This technique reduces computation time and memory usage using complex-variable asymptotic approximations around “poles.”

  • General Contour Planes on Field Point Boxes

    Better visualize stress and displacement distribution by defining the counter plane in a desired orientation in the field point box.

  • Field Points Defined on Any Surface

    Pick any surface in your model and visualize the results of that specific area.
