A new analysis package has recently been introduced for supporting Autodesk Inventor 3-D modeling software. DesignSpace from Ansys is a simulation tool that is fully associative with Inventor. Attaching models to the DesignSpace database is a seamless process, one user reported, and these designs are updated when changes are made to the Inventor models. The analysis software operates in a Windows environment and is priced at $6000 for analyzing two or more parts. A trial version can be obtained through the company?s website (see below).
