Method and system for transferring state variables in adaptive mesh-free analysis

摘要

A method and system for transferring state variables between an old and new model in an adaptive mesh-free analysis is described. The old and the new model are associated with a set of old and new integration points, respectively. A third set of nodes is formed to include old boundary nodes and the set of old integration points. For each of the new integration points, a sub-set of the third set is defined. The support of each node of the sub-set covers the new integration point to be evaluated. A local interpolant with a desirable consistency condition and interpolation properties is constructed to interpolate state variables at the new integration points. All of the non-interpolated approximation can be transformed into the interpolated approximation with the desired consistency condition and smoothness using this procedure.
