Meshfree Modeling and Analysis

The Semi-Analytic Geometry Engine (SAGE) Version 3.11

General Information

The Semi-Analytic Geometry Engine (SAGE) is a computer system for meshfree analysis. The SAGE employs the R-function method (RFM), which allows all given boundary conditions to be satisfied exactly without meshing the geometric domain. The present public release (Version 3.11) of SAGE is tuned to solve two-dimensional heat transfer and plate natural vibration problems on multiply-connected curved polygonal domains (i.e. polygons with holes bounded by linear edges and arcs). SAGE restricts the complexity of the geometric models to not more than 25 boundary pieces (edges), and provides a fixed choice of the basis functions for each type of problem. A full version, as well as many other types of solvers, including linear elasticity and thermo-elasticity amongst others, are implemented in FieldMagic, a commercial solver based on the same meshfree technology. Information of how SAGE can be used to perform other types of analysis, as well as its computational infrastructure, and numerical implementation can be found here.
