Hi everyone,
Currently having some problems with determining the contact tools to use for joining my shelled structure together.
The automatic constraint tool seems to not work, even when I specify the contact type to offset bonded with 1.2x the distance from the edge to surface. When I run the analysis I get the error of T2135 and within the help, it isn't quite clear how to stop this from happening as it directs to the main Nastran help section, not In-Cad.
However, I then tried to specify the contacts manually using the surface to edge, as generally the sections of the girder are but welded or seem welded.
I need to use shells as I need to determine the buckling load of the girder and assess the reduction in the buckling from the unstiffened to stiffened section.
I have attached some photos showing the section and the mid-surface planes used for the shell elements.
Thank you for the help, the questions I've asked already have been answered and have gotten me to where I am with this model 🙂
Let me make sure that I understand your model.
Hello John!
I shall do the listed methods below again to see if anything I've done was wrong.
I will add though, I made the mid-surfaces within the Inventor simulation tool, as this was much quicker than the one built into In-Cad.
Would this of made a problem?
Hi Chris,
You mentioned that you had also used the Inventor simulation tool to create midplane surfaces and wondered if that had some affect on the Nastran InCAD analysis.
I do not know for sure, but I suspect that the data is stored separately, so nothing done in the Inventor Stress environment should have any affect on the InCAD environment.
Let us know what you find out.
