Optimizing stress analysis calculations in Inventor 2010

I wish the Software was more publicized because its as useful to a Structural Engineer as it is to an Architect to a Sculptor Artist to anyone who wants to design anything from a pen to an industrial part.

I have a number of issues with this demo. In the book shelf example, the biggest problem was that you were loading out-of-plane on a surface that was only one element thick. This prevents the bending loads that are clearly generated from forming stresses. Adding refinement won't help since the stress doesn't exist.

In the welded example, a similar problem in the C-channel. But the biggest problem was the inside corner of the "no-weld". This creates a stress singularity that cannot converge.

I'm currently working on the optimization of a wind turbine tower and I'm having a few problems with FEA. I'm using Inventor Professional 2010, and it seems unable to calculate such a complex mesh... can anyone give me tips about this?

@therieri You should look into a package that has shell elements. They are a bit different in how you set up the analysis, but they would be much more efficient than the tetrahedral solids in IV Pro. (A good rule of thumb is to use shells if the part thickness is less than 10% of diameter.) Autodesk purchased Algor for the more advanced capabilities. Good luck!

2009 Inventor Pro only have part analysis.2009 Inventor also don't have parametric and convergence options.

Is the stress analysis calculations in the inventor 2009 pro?
