A standalone finite element code for structural analysis and design. Implemented in MATLAB. Uses Nastran input formatting.

NASTRAN Compatible Finite Elements (CoFE) is a standalone finite element code for structural analysis and design. CoFE is an open source program implemented using object-oriented MATLAB.

CoFE Version 4

CoFE v4.0 is the latest stable version. This version occupies the current (master branch and is archived as release v4.0).

CoFE v4.0 models are defined using NASTRAN-formatted input files (bulk data section only). Case control and optimization inputs are defined using MATLAB. Examples are provided to illustrate the straightforward process of creating analysis and optimization cases. A simple GUI is provided for previewing model inputs and viewing analysis results.

A CoFE v4.0 web user manual is maintained on the gh-pages branch of this repository and can be reviewed here.

CoFE Version 5

CoFE v5.0 is currently under development and occupies the version5 branch of this repository. This version completely reshapes the program architecture to allow for the sustainable addition of several new features that include

• Rectangular, cylindrical, and spherical coordinate system support for both node definition and nodal displacement reference frames
• Simplified source code organization through
  • Improved object composition using
    • heterogeneous object arrays
    • hierarchical object interfacing
  • Restructured class responsibilities by separating classes used for
    • input processing
    • model definition
    • analysis solutions
    • postprocessing

Significant v5.0 development progress has been accomplished; however, CoFE v4.0 is recommended for any user analysis at this time.
