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.
