Abstract
Finite element analysis methods and computer systems for analyzing deformation to an object are disclosed. According to various embodiments, the method includes the steps of: (1) performing a partial analysis on the object to generate a deformed boundary for the object from an undeformed boundary for the object; (2) generating a first deformed input mesh for the object based on the deformed boundary; (3) mapping node locations from the first deformed input mesh to the undeformed boundary for the object; and (4) performing an analysis on the undeformed boundary of the object using the first deformed input mesh.

- generating a first deformed input mesh for the object based on the deformed boundary;
- mapping node locations from the first deformed input mesh to the undeformed boundary for the object;
- and
- performing an analysis on the undeformed boundary of the object using the first deformed input mesh.
A system for performing finite element analysis to analyze deformation to an object comprising:
- a finite element analysis module for performing a partial analysis on the object to generate a deformed boundary for the object from an undeformed boundary for the object;
