What is best practice for FEA of assemblies?

HiI am rater new to Creo Elements, using release 5 from 2009. On a regular basis, we need to do standard static analysis on welded details, such as the one shown on the screenshot. The heigth is about 360mm and weigth 4.4kg material steel. The item is fixed by bolts in the horizontal

Did you have intf3d_in_as_part set to yes when you imported the step file? If not then change that and try it again.

If you are looking for how to keep a simulate model separate from the design model yet be able to be updated, then I would look at using inheritence models. There is an old PTC User presentation that explains this:

Hallo Paul

Thank you for the model you uploaded. I could not figure out how to do the copy and solidify step, but I found an equally simple method: Insert-Shared Data-Merge/inheritance. Maybe you use a newer version of Creo, we use Creo 1, also called Creo elements/pro 5.0 from 2009

This method has several advantages to the export/import method (2) in my original question, so I think that we will test it out. But other ideas are of cause welcome still

I have not yet read your paper, it is mainly about the stresses in the welding I see, which is not what I am looking for at the moment. But I'll go through it later (I do read German)

my method is without AAX:

STRG+C
STRG+V
ENTER
EDIT->SOLIDIFY... (Wildfire 5)
ENTER
STRG+A

Ok, now I get it.

I am not sure if my method requires AAX, but I think that the results are pretty much the same

For Info to other users with keybords that are similar to mine:

In Pauls description STRG+C Means pressing the <Ctrl> and the <C> key at the same time

I think Your method is good for our purpose, Paul, so I'll grant it the 'correct answer'
