Totally agree with israelkk on this one.
I did some similar research, which showed the effect of a pin in a hole.. see attached pictures.
I am not completely sure what you mean by rigid pin and a contact set...
I would advise on doing some analysis with a solid plate/pin...
I played around with your models a bit.. this is what I got..
Got the bumps out of the last model,
The first model you posted, I couldn't get it to work properly.. bumps are diminished though, but the last sweep(7) doesn't seem to...
@ TheTick... this often leads to Mesh-problems in the end... in my opinion it's best to make a new model to edit for your FEA or work with good contact-sets in your copied assembly
I needed to order a new workstation @ work..
My first choiche was to go for a Dell T3500, with a One Intel® Xeon® W3530 , 6gigs of ram, FX1800..
But our reseller advised me a T1500, with a One Intel® Core™ I7-880, 8 gigs and a Quadro 600, because of the rendering/FEA work we do, these...
As Eduardo says..
The HOW is very usefull, use the displacement-result and let it animate, you'll see in which directions you can make your design stiffer..
I suggest you go and try out some MOTION studies, this module has got lots of ways to display what you need... angle's, velocity's, resultant forces etc... this it not something you'll learn in a day though.
I'd say, use split-lines, then create several sketches (through "convert-entities") onto different planes...
