Hi all,
I use Creo 2.
I would analyze this assembly where we have two identical parts composed by a thin plate with 8 holes (for bolts that are simulated as fasteners) and a thin tube that is weld on the plate.
This two structure are assembled together with the bolts, they are constrained at the bottom and there is a bending moment at the top.
In the first test I have meshed all with shells and I have inserted a contact surface between the two plates; but the shells don't support the contact regions.
In the second I have meshed the plates with tetra and the tubes with shells; Creo has meshed but there was so much tetra, due the very thin plate (6 mm) that I suppose it should take many hours to converge...if it can...
In the third case I've tried to mesh the plates with the mapped mesh control, in an attempt to have a more regular mesh with few elements. But I'm not able to link this mapped mesh with the tube above the plate.
Any suggestions?
