Thanks for the response. What you said does make sense now. I was probing the high stress elements and using the values from the integration points of the element to avoid any extrapolating to the nodes.
Thanks again.
I have a bracket modeled with shell elements which is constrained on one end and loaded on the other. I also have defined the elastic and plastic data for aluminum material, with the last two data points defined such that the slope is perfectly plastic after 4% true strain.
I noticed that when...
The main alternatives to Patran for pre/post-processing of Nastran models are Femap and Hypermesh. Both are usually cheaper than Patran in cost.

Most Aerospace companies use Patran because it was the first to take root in that industry (just like Hypermesh has a foothold in the Automotive industry). After making such an investment in money, training, developing procedures, etc. it's hard to change.
I've found that whatever application...
The 2D elements provided "layered" results, while the 3D elements provide "non-layered" results. In the "Results" menu select "layered" to view 2D elem results, and "non-layered" to see the 3D elem results.

To submit your Nastran job from inside Patran, you need to adjust a configuration file so that Patran knows where the Nastran executable file is located. If you've installed Patran and Nastran locally on your workstation, you need to edit the file called P3_TRANS.INI which is located in the...
Normally, a sandwich panel can be modeled two ways:
1) Represent the face sheets and core as a composite, where the core is simply a "thick" lamina ply.
2) Model the core as a solid (usually, HEX8 elements).

With the latest version of Nastran (2008) you should use the following line in the .rcf file:
notify=no
I don't think the msgbell argument works any more.
