Simulation Solvers

Function-based processing for the FFEPlus iterative solver is extended to frequency and buckling studies, and to the linear static studies that include node-to-surface interactions and virtual wall definitions.

  • FFEPlus Iterative Solver

    The transfer of stiffness data to solve the systems of equations is optimized for linear static, frequency, and buckling studies because file-based processing is replaced with function-based processing. Solution performance is improved for frequency and buckling studies. The image illustrates the solution performance for a typical frequency study.

    In addition, solution performance is improved for linear static studies that contain:
    • Node-to-surface bonding and contact interactions
    • Virtual wall definitions
  • The FEEPlus and Large Problem Direct Sparse solvers can now handle multiple translational and rotational degrees of freedom that are applied remotely with the distributed connection type.
