Welcome to the Autodesk Inventor Nastran Forums. Ask questions, share your knowledge, and make connections.
For beam models, Nastran normally will automatically split the sketch lines where two lines intersect so that the beam elements are connected together. Normally.
Hi @Anonymous Why do you say that applying a load to the top of the plate concentrates it in the middle of the plate? Have you run the analysis? Inventor Nastran does not work that way. The load (whether a force or a pressure) is distributed over the selected geometry. If you apply a force to a face, it behaves like a pressure (=force/area of face). If you apply a force to an edge, it behaves ...
The solution was using the Automatic button in the Nastran ribbon to automatically create contact sets between touching surfaces. Once I elected that feature, I was able to run the simulation in Linear Static just fine.
I am having the following problem: Instead of using the temperature dependent alpha over the range between Tinitial and Tload to calculate the thermal expansion, nastran uses only the alpha at Tload.
Welcome to the Inventor Nastran forum. First, you should create a new post because your model, problem, and solution are likely to be completely different from the original post.
Hi @charrigan6B552 . Welcome to the Inventor Nastran forum. Constraints connect the model to the ground. In your situation, the tee pin connects the shaft to the frame. No type of constraint applied to the shaft will mimic that exactly. The load that is transferred to the constraints goes into the ground instead of into the frame. Depending on how tight the tee pin is in the hole through the ...
