ASAS is an offshore structural finite element system with integrated modules to address the specific needs of offshore and marine engineers. It provides an integrated facility for performing structural assessment of most types of offshore/marine structures including jackets, jack-ups, concrete gravity-based platforms, risers, FPSOs, TLPs, semi-submersibles and, of course, ships.
Two packages are available. ANSYS ASAS provides a general purpose analysis capability with linear and nonlinear options including code checks for framed structures (i.e., joint checks and member checks). ANSYS ASAS Offshore extends ANSYS ASAS to include modules for wave loading, soil-pile-structure interaction and spectral fatigue due to wave, current and wind loading. Model creation can be performed via ANSYS® or with FEMGV®.
ANSYS ASAS is highly appreciated because of the following distinguishing capabilities, including:
Coupled wave/current/wind-structure interaction with nonlinear structural response
An integrated results database which can be accessed by MS-EXCEL© and Mathcad©
Deterministic and spectral fatigue analysis capabilities (e.g., for jackets and flare towers)

Combine the premier software package for explicit nonlinear structural simulation with one of the industry%u2019s most recognized and respected finite element pre- and post-processors, and you get ANSYS LS-DYNA, the result of a collaborative effort between ANSYS, Inc. and Livermore Software Technology Corporation. First introduced in 1996, ANSYS LS-DYNA%u2019s capabilities and robustness have helped thousands of customers in numerous industries resolve highly intricate design issues.
Limited-duration events (such as severe collisions and blade containment) and large, permanent deformations (within the stamping and forming industries) present engineers with unique simulation challenges. ANSYS LSDYNA meets these challenges by fusing LSTC%u2019s LS-DYNA explicit dynamic solver technology with the pre-/post-processing power of ANSYS software. This powerful pairing helps engineers understand the elaborate combinations of nonlinear phenomena found in crash tests, metal forging, stamping and catastrophic failures.
ANSYS LS-DYNA supports both 2-D and 3-D explicit elements, and features an extensive set of single-surface, surface-to-surface and node-to-surface contact as well as a contact analysis option that automatically creates the contact surfaces. ANSYS LS-DYNA also gives optional methods for fast solution processing. The symmetric multiprocessing (SMP) and massively parallel processing (MMP) methods optimize the power of multiple CPUs to deliver explicit simulation results in a fraction of the time.

Flux is a general purpose CAE software which only requires that one clearly describe their idea. This is done by defining the individual components which make up the idea in each of the following areas:
- Physical shape, or geometry
- Relative location and orientation
- Mesh or discretization
- Material character
- Excitation or energy source for the idea
Flux then solves for the requested physics and provides one with multiple ways to scrutinize the solution, and to review the success of the idea. You can view the results in many different ways to clearly scrutinize your design idea. You can use color-shaded maps or isovalue lines within the problem region to look at quantities like flux density or heat distribution. You can use variation curves versus time or position, or make spatial spectrum computations. Additionally you can analyze global quantities like inductance, energy, force and torques.

SAMCEF Linear is a general purpose Finite Element Analysis package.
SAMCEF Linear is driven by SAMCEF Field, the interactive graphical user interface for the modeling, the analysis and the post-processing of structures.
The linear analysis of complex structures can entail the pre-processing of a huge amount of data. SAMCEF Linear benefits from advanced visualization tools, allowing very efficient and straightforward pre- and post-processing of linear analyses.

Nozzle/Pro is designed specifically for the instances where excessive conservatism or dangerous designs might result from dated and often inadequate simplified techniques. Nozzle/Pro is 'sharpening the pencil', and eliminating uncertainty in a calculation. If a WRC 107 method, for example, in cases where WRC 107 estimates a result within plus or minus 150%, Nozzle/Pro can and will produce a result within 15% and will produce it much faster.
* Nozzle/Pro is easier to use than WRC 107 and far more accurate
* Nozzle/Pro produces stresses in straight, pad reinforced or barrel reinforced nozzles, and structural attachments in spherical, dished, elliptical, flat or conical heads and cylinders using the finite element method.
* Nozzle/Pro is also automatically used by Compress, AsmEQuip or Code Calc. If you have one of these products, you can automatically produce finite element results using Nozzle/Pro.
* Nozzle/Pro produces 3d models and "inspector ready" reports in an easy to read HTML format that can be reviewed by anyone with an internet browser

Getting your CAD geometries ready for FEA modeling is easier than ever with the CAD Import Module. It facilitates the reading of industry-standard formats such as STEP, IGES, ACIS® (SAT®) or Parasolid®. Extra add-ons support file formats for packages that have their own geometry kernel.
The CAD Import Module goes beyond just the reading of file formats. The interactive repair feature assures that imported geometries are mathematically correct for FEA modeling. And, in order to cut down on unnecessary details in your CAD geometries, defeaturing tools that remove fillets, small faces, sliver faces, as well as spikes or short edges are included.
The CAD Import Module also provides bidirectional interfaces to SolidWorks® and Autodesk® Inventor® that maintain associativity with these CAD systems. This means that geometric parameteric sweeps can be run using the COMSOL models, which result in automatically updating of the CAD geometry in the corresponding CAD system. Such parametric studies can also be run using clusters and can be set up directly from the user interface. For a list of supported versions, see the System Requirements page.
