NX 10 advanced simulation, overlapping displacement result with model. Is it possible? 1

NX 10 advanced simulation, overlapping displacement result with original model. Is it possible?

And second question, how can I show stress inside the solid body? I can't find any setting that allow me to see what is going inside the body.

Enjoy your work and have fun!

I'm going to assume you mean that when you scale the displacement so it is true scale (not amplified by some factor); then you get an image in which the part collides with itself. You did not properly set up your model. Perhaps you need to define some contact between surfaces.

I interpreted that as "I'd like to view the original (undeformed) model at the same time as the deformed model for comparison". If this is the question, one way to do it is to set the deformation scale to 1:1, then export a jt file of the deformed result. The jt file can be imported back to the original model to overlay the results. Note that you won't be able to do much measuring with the jt body.

For question 2, there is a way to define a cut plane to show the results on the interior of the body. On the post view display tab, there is an option to display results on the cutting plane.

Cowski is correct. I saw that ANSIS has this function where you can see undeformed model and deformed model in same view so you can compare them. I was curious if that option is available in NX.
Also ANSIS has cut that show nodes and elements inside body. All I could find is Clip Section tool in NX, is that what you refereed to Cowski or I am missing something?

I was referring to the clip section tool; there is an option in the post view to color the section cut according to the results so that you can see the internal stresses. I think that there is another type of cut that works by showing/removing entire elements, which results in a jagged looking cut through the model. However, I might be confusing another FEA package that I used in the past with the NX FEA; it's been a long time since I used that option.

OK...
1. To show UNDEFORMED MODEL in same view together with deformation/stress or any result go to RESULT tab, click on EDIT POST VIEW icon (yellow wrench icon) and in DISPLAY tab check on SHOW UNDEFORMED MODEL.

2. To see inside model, go to RESULT tab, click on EDIT POST VIEW icon (yellow wrench icon) and in DISPLAY tab change last option DISPLAY ON to CUTTING PLANE. Then click on OPTIONS button next to it (it become selectable when you set display to cutting plane).
In option click on counterclockwise icon to see update in real time.
set cut plane as you like in top section options CUT PLANE. Then when you move slider you will be able to see colors inside model. If leave options window by clicking OK, section will stay in main graphic window and you can then change solution results to see how it look in that section of model.
Show feature edges and Show clipped ghost are interesting functions too when combined with possibility to change solutions in main window.

Cowski, jagged looking section is from ANSIS.
