Computer Aided Engineering (CAE) - Finite Element Method (FEM)

Geometry Clean-Up and Fixing

Geometry translation between CAD systems sometimes results in corrupt or incomplete geometry/topology. Some preliminary operations must be performed:

• Checks for geometrical and topological inconsistencies
• Fix geometry problems by healing if real geometry
• Fix topology and virtual/faceted geometry problems by deleting and reconstructing entities
• Healing: Fixes underlying real geometry
• Corrects tolerance problems in the model and attempts to connect coincident edges and form volume from connected faces
• Rebuild/reconstruction of unsuccessfully fixed parts

Modelling Techniques

For building and editing models, we use a sophisticated suite of tools. For 2D and 3D model creation, users have access to a variety of mesh generation programs as well as the most powerful meshing modules in order to perform:

• Automatic meshing
• Semi-automatic meshing
• Manual meshing
• Element type
  • 2D Elements
  • 3D Elements (tetra, brick, wedge)
  • P-Elements
• Boundary condition modelling
• Special Techniques
  • Welded joints
  • Contact modelling

Our expertise allow to build the best model and to perform the most suitable and accurate FE analysis.

Model Checking

Models must be carefully validated and approved before any calculation be performed:

• Quality checks
• Run checks

Pre-Post Processing

We can interface with:

• Patran
• I-Deas
• Hypermesh
• Femap

Solver Interfacing

Our models support a host of different solver formats for both import and export. Along with fully–supported solvers, we also provide the flexibility to support additional solvers via a complete export template language and C libraries for development of input translators:

• Nastarn
• Abaqus
• Ansys
• Cosmos
• Dytran
• Pam Crash
• LS Dyna
• Samcef
