ADINA Advanced

ADINA

ADINA is the premier finite element program for nonlinear analysis. ADINA Structures and the ADINA User Interface are used to solve the most difficult nonlinear problems involving:

• Geometric, material, and load nonlinearities
• Large deformations
• Contact conditions

State-of-the-Art Stress Capabilities: ADINA Structures

For the analysis of solids and structures, the analysis can be linear or highly nonlinear, static or dynamic. Take advantage of versatile and generally applicable finite elements for solids, shells, beams, trusses, pipes, and special purpose applications. Material models are provided for metals, soils and rocks, plastics, rubber, fabrics, wood, ceramics, and concrete.

Analyze Multiple Element Types

Conduct linear and nonlinear analysis of solid elements (2D and 3D solid elements), structural elements (truss, beam, pipe, shell, spring, optimal shell elements, MITC3+, and MITC4+), fluid elements (2D and 3D potential-based subsonic fluid elements), acoustic elements, special purpose elements (alignment, connector, general), or user-defined elements.

Minimize CPU Time and Memory Requirements

Deploy structural-only analyses, or use with other modules in the product suite for multi-physics applications, such as thermo-mechanical coupling or fluid-structure interaction analyses. Powerful solvers and element formulations enable the analysis of extremely large models with minimal CPU time and memory requirements.

Complete Pre- and Post-processing Capabilities with ADINA User Interface

Benefit from a fully interactive graphical user interface for all your modeling and post-processing tasks. Model geometry may be directly created or imported from various CAD systems, including those that support Parasolid (NX, SolidEdge, and SolidWorks).

Fully Automatic Mesh Generation

Meshing for 3D elements includes mapped meshing that generates brick, wedge, or mixed free-form tetrahedral elements, and general 3D meshing for solids and fluids. Conduct 2D surface meshing for shells, plated, and 2D planar elements, as well as 1D elements, such as truss, beam, and pipe.

ADINA CAD/CAE Interfaces

ADINA User Interface provides full capabilities for pre- and post-processing all the ADINA solution modules. Depending on what you are most familiar or comfortable with, the following interfaces can be used effectively with the following systems:

• Parasolid – The ADINA Modeler (ADINA-M) which is based on the Parasolid kernel provides a natural interface to all Parasolid-based CAD systems such as NX (Unigraphics), SolidWorks, and SolidEdge. (The Parasolid Interface is not included with ADINA, ADINA Advanced, or ADINA Ultimate. The ADINA Parasolid Interface is an add-on and requires a Parasolid Interface Virtuoso Subscription)
• IGES – The IGES interface is primarily used for geometry from CAD systems where a direct interface is currently not available (e.g., CATIA).
  Open Cascade – The ADINA Modeler (ADINA-M) which is based on the Open Cascade kernel provides a natural interface to all the CAD systems that support Open Cascade (e.g. FreeCAD, CAD Exchanger, and Datakit).
• STL – STL (stereolithography) files obtained from scanned 3-D images or CAD objects (e.g. from AutoCAD) can be imported into ADINA. ADINA creates the necessary points, body edges and faces that can be used to define finite element meshes and also loads and boundary conditions.
• STEP – STEP (Standard for the Exchange of Product model data) files can be imported into ADINA with the ADINA Modeler for Open Cascade.
  Point Cloud – ADINA imports the point cloud data resulting from 3-D scanning and creates solid objects that can be saved in STL format for further processing.
• Femap – Femap finite element models are translated for analysis using the ADINA Structures, CFD or FSI program. The analysis results can be viewed in the Femap neutral file format.
• NX (Simcenter 3D) – NX (Simcenter 3D) can be used as a pre- and post-processing environment for ADINA. Models generated in NX can be imported in Nastran format into ADINA and the results from ADINA can be imported into NX for post-processing in universal file format.
• Nastran – Nastran input files can be imported directly into the ADINA User Interface program. In addition to reading the regular Nastran input, additional NX Nastran commands, e.g., for 3-D contact definition, are also supported. Special features are available to make the application of additional loads and boundary conditions on the model easier. The ADINA results can be output in the Nastran op2 file format for post-processing by other systems.
• EnSight – From the ADINA User Interface, results obtained from ADINA structural or CFD analyses can be exported in EnSight Case format. The user can view these results in the EnSight post-processing environment by importing the Case files.
