Patent ID: 8612186

Claim:
A computer-implemented method of simulating structural behaviors of an engineering product, the method comprising: receiving, by an application module installed in a computer system, a finite element method (FEM) model representing an engineering product, said FEM model comprises a plurality of FEM elements; creating, by said application module, a meshfree enriched FEM (ME-FEM) model by adding at least one meshfree enriched (ME) node into each of a subset of the FEM elements, said at least one ME node is configured to eliminate volumetric locking; and obtaining, by said application module, numerically-simulated structural behaviors of the engineering product using the ME-FEM model, wherein said application module is configured to perform a meshfree enriched finite element analysis that employs a displacement-based first-order convex meshfree approximation and an element-wise interpolation possessing Kronecker-delta property at said each of said subset of the FEM element's boundary allowing essential boundary conditions to be applied.
