Public Domain Software
The following describes the major public domain engineering software packages that are owned or licensed by INTECSEA. Public domain software represents software packages available from engineering companies that deal solely with designing and developing programs. In addition, several utility programs are used by INTECSEA that are not listed. More detailed descriptions of these programs are available upon request.
Structural Analysis - ANSYS
ANSYS is a multi-purpose FEA analysis program used by various engineering disciplines: structural, mechanical, electrical, CFD, etc. INTECSEA utilizes a few of the modules, available in the suite of programs, ANSYS/Structural, ANSYS/Professional and ANSYS/Prep Post.
INTECSEA uses the most current version of this software available to the industry.
- ANSYS/Prep Post
This ANSYS module has the capabilities to create finite element models and to analyze results after analysis is completed. This module does not have FE problem solution capabilities. - ANSYS/Professional
In addition to the ANSYS/Prep Post capabilities, this ANSYS module enables the user to perform linear static and dynamic structural analyses. Dynamic analyses include modal, harmonic, transient, and spectrum analyses. This module also has some non-linear capabilities such as large deflection and stress stiffening for some elements and node-to-node contact elements. - ANSYS/Structural
The module possesses all of the capabilities of the ANSYS/Professional module. In addition this module can perform transient thermal analysis, non-linear buckling analysis and p-method structural static analysis. The program also allows the user to solve fracture mechanics problems, model composites and perform fatigue analyses.
In addition to the readily available capabilities in the ANSYS program, INTECSEA has also developed several tools using ANSYS APDL capabilities to automate several of the structural engineering processes.
SACS
SACS is an interactive, graphics-oriented structural analysis system program developed by EDI. It is commonly used by the offshore industry to design and analyze truss type structures – fixed offshore structures and topsides structures of floating platforms.
The following are some of its main features:
- Perform wave load calculations, stress analysis, and member designs
- Unity checks capability in accordance with various codes
- Perform soil-structure interaction analysis, taking into consideration the non-linear properties of the soil with the pile and the structure
- Perform eigen and seismic analysis in the dynamics module
- Perform fatigue calculations by either the deterministic or spectral method
- SACS/WAMIT capability – provides interface between WAMIT and SACS
