DIMENSIONAL REDUCTION OF FINITE ELEMENT ANALYSIS SOLUTION FOR RAPID EMULATION

摘要

An example method of analyzing a structure includes generating initial simulation results for at least one finite element model, each of the at least one finite element models includes a plurality of nodes representing a structure. The initial simulation results simulate a response of the plurality of nodes to boundary conditions for a plurality of sets of input variable values. Each set of input variable values represents a different geometry of the structure or a different set of boundary conditions. The initial simulation results are decomposed into a plurality of patterns that indicate correlations between values in the initial simulation results. The plurality of patterns has a quantity that is less than the plurality of nodes. A respective emulator is created for each pattern. The initial simulation results are expanded by determining additional simulation results for the plurality of nodes using the emulators and additional sets of input variable values.
