Sefea is one of the newest generations of enriched finite element methods. This white paper explains how Sefea:KeyCreator Analysis with Sefea Technology was developed specifically for low-order 4-node tetrahedron and 3-node triangle in the CAE environment, achieves the accuracy of 2nd-order elements such as 10-node tetrahedron at the low-order element computing cost and robustness without the 2nd-order element side-node noise. can withstand user abuse with tolerance for mesh density variation and distortion, which commonly occur in an automatic tetrahedron mesh generator in CAE. and how Sefea's unified enrichment method is suitable for fully coupled stress, thermal, fluid, and EM physics in an integrated multiphysics formulation. Read to discover how Sefea can solve more realistic problems that were not feasible in the past, as well as see illustrations of the three of the most valuable characteristics of Sefea in CAE applications: Achieving 2nd-order element accuracy while using easily generated first order tetrahedral elements. The ability to use finer mesh without exponentially increasing computing cost, as is often needed in many nonlinear heterogeneous problems, and Robustness without the risks of higher-order element side-node mesh distortion and noise.
