This method based on modified nodal approach is easy to set up the fault diagnosis equations and has lower degree of nonlinearity and regular Jacobi matrix form.
The enriched basis is formed from a union of the set of nodal shape functions with a set of products of nodal shape functions and the enrichment function.
