About Jerry Greenough

I am a freelance developer of scientific and engineering software. I have extensive experience writing numerical software in Python and C++.

Here is a summary of my commercial and academic career to date. If you wish to know more about how I can be of service, please feel free to contact me.

Employment Experience

2001 - 2016: Engineering Dynamics, Inc., Bentley Systems, Inc. in New Orleans, LA.

Responsible for the maintenance and development of numerous programs from the SACS^® system. (SACS^® is a suite of Engineering software modules that are used widely in the Offshore Oil Industry). Duties entailed the restructuring, interpretation and debugging of legacy code as well as developing new functionality. Areas of work have included non-linear finite element development, formulation of non-linear solution techniques, solution of solid-modeling problems and the development of meshing algorithms. Also developed DOS scripts for the compilation and execution of QA tests. Developed a solid modelling console app. for the rendering and meshing (using Delaunay triangulation) of multiple chord-brace type beam intersections.

Particular interests included the development of FE technques to model fixed offshore structures exhibiting both geometric non-linearity such as column buckling and laterial torsional buckling, as well as non-linear elasto-plastic behavior due to isotropic strain hardening. Additional work was undertaken on the non-linear effects of pile-soil interaction.

1997 - 2001: Femsys Ltd, U.K.

Responsible for developing and maintaining a wide range of functionality for the finite element Pre- and Post-Processor software Femgv^®. Programming duties entailed the creation of solid modeling algorithms, computer-aided geometric algorithms, data manipulation and tabulation, development of meshing algorithms, creation and documentation of an API. Developed a paving algorithm for the automatic generation of quad elements. Implemented a BREP object required to host a tetrahedral mesh. This necessitated the development of a Jarvis March type of algorithm for navigating the surfaces of the BREP object in order to retrieve the outer surfaces required for a triangular 'seed' mesh.

1994 - 1997: Defence Research Agency, U.K.

Responsible for analysis tasks relating to structural and material characteristics of submersible platforms. Duties entailed the development of software for the modeling and visualization of magnetic material properties, as well as running a number of electromagnetic FE models.
