To analyse designs to ensure that they withstand all loads without failure have been both important and possible for a long time. In the early days of FEA-simulations, the pre-processing was a very laborious task. Since almost all of today's designs are in 3D a natural choice would be to choose an analysis software that can directly work with 3D models.
We design in several different tools depending on the characteristics of the problem. We do a lot of work in Inventor Professional, an excellent FEA tool, which is nice and easy to use and at the same time fast and accurate. The cost is small and we have helped so many designers to step into the design world. In our highly valued training led by experienced engineers, we have developed our customers from insecurity to security.
Where Inventor Professional becomes limited in terms of analysis capability we have helped customers to move up to Nastan In-CAD. Nastran In-CAD extends your analysis capabilities to include Bolted connections, buckling, fatigue, thermal, Non-linear analysis and much more, all with the familiar working environment of Autodesk Inventor.
Symetri can also help you via consultancy in the event you are under tight timescales.
