connectors

Guys,

I am new to Hypermesh and bit (actually a lot) confused with welding and bolting connections. Can anyone help me out regarding the below questions..

(1) I have to connect two components with M5 fasteners. I have mid-surfaced, meshed the surfaces and created the spider for holes. Now I have to select the centre nodes of both the holes with a bar/rod/beam element. Here is my confusion. What I have to select here? Where to give the dia of the 1D element. Do I have to give the properties for the new 1D element as well.

(2) Same problem and if I have to do spot weld instead of bolted joints (assuming no holes there), which option I have to select and where to give the dia of the spot weld for example 7mm dia.

Thank you very much in advance.

Did you go through HM tutorials? if not please do it, it's very simple, will take half hour(connector tutorial, 10 mins for bolt tutorial) and does exactly the same thing which you are asking.

Bascially, go to HM help on your dirve and Hypermesh > Hypermesh Tutorials > Assembly.

All the best.
