Automatic Iteration with FEA - HyperSizer uses FEA computed element forces to size a structure’s panels and beams. After optimizing a structure’s cross sectional dimensions and selecting the optimum materials and composite layups with these forces, HyperSizer will generate the FEM data for the next iteration of FEA internal computed loads. This coupling process has in the past been manually iterated. Now with HyperFEA™, this process can be automatically iterated until convergence is achieved. After updating the FEM element stiffnesses, HyperFEA submits the NASTRAN FEA solution, and reads the results for the next HyperSizer sizing optimization. HyperFEA also interactively plots weights of panels and beams as it iterates.
