A method of creating a CAD model from a finite element model includes identifying and characterizing features of interest from the finite element model. Multiple intermediate data structures of the finite element model are created by dividing the input mesh of the finite element model into mesh regions. Feature recognition is performed on each intermediate data structure to identify finite element model features. Features and feature properties are extracted from the finite element model, and a CAD model is created using the extracted features and feature properties.

Converting finite element models to CAD models using feature recognition

One embodiment relates to a method for detecting self-contact in a simulated object. The method includes detecting contact region within a simulated model, classifying the contact region in the model. The method further includes fixing the contact region by at least one of moving a node in the model, local modification and Boolean operation and creating a tetrahedral mesh after fixing the contact region.

Mesh component design for finite element methods and systems

A method for generating a finite element mesh that includes receiving, by a computer system, data regarding a model of a simulated object, categorizing one or more geometric features of the model and dividing the one or more geometric features of the model into surface shapes based on the data regarding the model. The method includes generating a mesh for each surface shape; and interconnecting the generated mesh to form a mesh for the model.
