FEANexus is a novel FEA pre-processor intended to facilitate efficient, automated simulation-based design (SBD) processes delivering reliable results for decision making.
FEA analysts tasked with creating and analyzing virtual prototypes are faced with a number of tedious and time-consuming tasks. These include generally:
- CAD geometry translation
- Geometry cleanup
- Manual meshing processes
- Re-applying problem physics (e.g. material, constraint forces etc.)
When time-consuming tasks coincide with a shortage of analysts, assuring timely availability of FEA results for design decisions becomes impossible.
FEANexus relieves FEA analysts from routine, time-wasting tasks through the implementation of the following three concepts.
- FEANexus avoids geometry conversion and clean-up efforts by using CAD system functionality to create the FEA mesh directly from the CAD model.
- The mesh is always created automatically, which accelerates this step in the simulation process.
Finally, FEANexus employs geometry-independent, re-usable Abstract Models to define an FEA simulation model. When combined with a CAD model, Abstract Models behave like a recipe to automatically execute the type of simulation they have been created for. Thanks to the automated process, they always create the same accuracy, comparable results, whether used by FEA specialists or product designers without FEA knowledge. Hence, FEA verifications can be performed when needed and not only when an analyst is available.
FEANexus System Overview:
An FEA simulation process based on FEANexus can be executed in two roles, authoring, and production.
Authoring mode involves the creation, editing, testing and debugging of an abstract model during the initial setup of the workflow. Authoring of abstract models is usually performed by FEA specialists.
Production mode means the automatic generation of an FEA mesh and solver input files by simply selecting a CAD model and corresponding abstract model.
FEA CAD Creation: This mode involves capturing/deriving simulation space in a CAD model using a smart combination of parametric, library and manual feature creation with the top down CAD modeling approach.
After FEA CAD and the abstract model file gets ready then the user can use Production mode for automatic generation of an FEA mesh and solver input files by simply selecting a CAD model and corresponding abstract model.
