stress analysis

Hi.........we have only just purchased inventor professional and want to use it to do some stress analysis on items we are fabricating. When we go to start the analysis, the program, (inventor) asks us to make the part "active"..............What does this mean?

Can anybody help?

To make a part active would be to select the part.

I have only used stress analysis in inventor once ( not got round to hard stuff :wink:

In inventor (standard program) there is nothing that says make a part active as u make the part active by double clicking it.

In Stress Analysis there are menu's like the Weldment had new menu's Tube and Pipe new menu's and the Studio has new menu's.

Try rightmouse click the part and Make Active should be in there hopefully.

or doubleclick the part then do a stress analysis.

If its 2 parts then make an assembly.

Ill have access to Inventor stress analysis on friday and will have a look for you if you like.

Thanks for that............we got things sorted now. Problem was more to do with us personally trying to adjust from Autocad 2005 to Inventor. The more we play around with it the better things come together. The displays and the reports available with the stress analysis software are fantastic.

can u show how to place a stress in a bottle pls...

what would it be......

Fill it with soda and shake:)

Can you explain a bit more what you are doing? In general you would apply a pressure to the inside faces of the bottle and your results would be the strain. The stress would be force per area.

You have to use the Select Other to get the inside faces - make sure you get them all. I often slice the part in half so that I can see inside and the surpress the sliced feature after applying the pressure.

Attach your file here if you can't figure it out.
