General advice need regarding assembly analysis
General advice need regarding assembly analysis
(OP)
I've been using Pro/Mechanica fairly succesfully for the past few months and now need to analyze a frame structure that is essentially a backbone of 2'x4' slab of steel, held up with gusset pieces to a base. There are some masses cantilevered off the backbone, and all the parts are bolted together.
I need to analyze the entire assembly, but haven't played around with specifying joints and such on Pro/Mechania yet. (wildfire version) What is the best approach for this? Do I need to specify my part connections, or is there a default type of connection that Pro/Mechanica assigns?
Thanks!

Please see the thread Simulating bolted joint connections (Thread828-73304). LTR is correct regarding the default assumption of a "welded" connection.

RE: General advice need regarding assembly analysis
An easy round way this is to adjust your assembly alignment;
Make sure that when you are locating a new component to an existing assembly, mate or align DATUMS or AXES.
Obviously this may not be as convenient as using existing surfaces, but spending several momments creating new datum planes will allow you to perform analyses on assemblies.
Whan you switch to Mechanica mode from Pro/Engineer, it will warn you that you have several components rather than one full assembled component. Check this number is what you expect!
