Implementation of the Smoothed Finite Element Method using 10-node Tetrahedral Elements into a General Purpose Finite Element Software

Abstract

An advanced smoothed finite element method using 10-node tetrahedral elements (SelectiveCS-FEM-T10) is implemented in a general purpose finite element software: ABAQUS. The implementation itself with the user-defined element (UEL) subroutine is successfully conducted; however, it turns out that the UEL is less-useful for ordinary users due to the various restrictions of UEL and thus it needs a native implementation.
