Trident FEA Basic package

The Trident FEA Basic package offers standard FEA capabilities, which can then be enhanced with additional analysis modules, data translators and other Trident software.

The Trident FEA Basic package includes:

• Pre/post-processor - Allows for detailed structural modeling, automatic mesh generation and refinement using an extensive library of elements. Comprehensive post-processing capabilities allow for in-depth visualization of the most complex analysis.
• Linear static analysis - State-of-the-art linear static analysis capabilities. The program produces displacements, strains, stresses, forces, and error estimates as results of the analysis under a variety of loading conditions.
• Top-down capability - Conduct coarse mesh global analysis and then refine the mesh for more accurate results in high stress areas.
• Fast sparse matrix solver - Trident FEA includes Martec's new sparse matrix solver, which dramatically reduces computation time (10x or greater).
• MAESTRO seamless integration option - For users of the Maestro ship building system, Trident FEA works seamlessly under a single user interface.

Additional Analysis Modules

Trident FEA Basic can be customized with any of the following analysis modules:

• Natural Frequency - Provides several eigenvalue analysis techniques to evaluate natural frequencies and their corresponding mode shapes.
• Buckling - Predicts the loads at which the onset of structural instability will occur.
• Dynamic - Performs dynamic response analysis due to time history loading, response spectra input, steady state harmonic input, and random vibration excitations.
• Nonlinear - Performs nonlinear static and dynamic analysis, including large displacements, plasticity, hyperelasticity, and post buckling analyses.
• Thermal Stress - Predicts thermal-induced stress and linear elastic deformations.
• Heat Transfer - Solves for steady state and transient temperature and heat flux distributions, including phase changes, due to convection, conduction and heat generation.
• Fatigue I - Basic fatigue analysis capability using Miners Sums and Fatigue Diagrams methods.
• Fatigue II - Advanced fatigue analysis allows simulation of crack initiation and propagation under deterministic and spectral loads.

Translators

A number of translators are available to allow the import and export of data files with other FEA and CAD systems including:

• CAD - Import and export data files in standard IGES format
• Nastran – Import and export data files with MSC.Nastran
• ANSYS - Import and export data files with ANSYS
• HyperMesh – Import and export files with HyperMesh
• USA - Import and export data files in USA format
• Patran - Import and export data files with MSC.Patran
