thank you for this tutorial matthew, please if you can give us the load-displacement curve of this lap-joint. and what concordance between the test and numerical solution
If you did not generate the surface regions then Nastran would not know that those elements were in contact with each other. The elements would then pass through each other and there would be no calculated contact forces or pressures.
+Matthew Jackson Thanks Matthew! In my simulation I did not define surface region, only mesh mating and my parts disconnect from their places. I'm going to define a the connection like you did.
Solid mouse click feedback.

If M24 bolt connection is used what should be the force applied in bolt preload, and part is of 7000 kg mounted on a block

If you have any requests then please ask???
+Matthew Jackson What happen if I don't generate the surface region?
