This project deals with the effect of interoperability between Computer Aided Design
(CAD) and Finite Element Modeling (FEM) software on structural modeling and analysis.
Several case studies were conducted, where a building information model was transferred
from CAD to FEM software with different data exchange formats. Based on interviews
and collaboration with several engineering companies, certain CAD and FEM software were
chosen for the case studies. A general structural analysis was made in the FEM software to
investigate if the model is imported correctly. The project also deals with data exchange
connected to advanced FEA, which includes a non-linear buckling and fatigue analysis.
The conclusion of the case studies is that, data exchange between CAD and FEM software
can be useful, but the ease of use depends on both the data exchange format and how
the model is created in CAD software. In these case studies, the most successful data
exchange was achieved with the direct link between CAD and FEM software compared to
open exchange standards. It is also concluded that while there are still technical barriers in
front of an effcient data exchange process between CAD and FEM software, especially for
open-source solutions, there are multiple ways to make it work fairly successfully. However,
in order for a more integrated design approach to be viable in engineering practice, current
methods of structural design and communication have to evolve and adapt.
