How to stress test digital models?

[Brickstarrunner]

It's been a while since I posted on Eurobricks, mostly because I sort of fell out of the Lego hobby for a while. Recently I began to pick up interest again and I dusted off an old Lego Digital Designer project I was doing before I took my break from it. It's a late 19th century railroad passenger car that is roughly around 800 to 900 bricks in total. I had the plan of buying up the necessary bricks I needed online via Bricklink, eBay, Pick-a-Brick, etc. to build my model. I don't have much experience with building models in real life other than the ones inside the pre-made instruction booklets, so I am unsure if my model would be able to hold itself together on its own or if part of the model/the entire thing would fall apart at the slightest touch. I tried to use techniques I already know, such as overlapping bricks to increase durability and such, but even then I'm not sure how much that will help.

Is there a way I can stress test a digital model to see if the structure is sturdy or not. To try and see what parts are rock solid and what parts may break off is given even a slight nudge. I don't have all the bricks necessary at home to create a test version and I'm rather stricken on money at the moment, so I'd rather not spend more than what I just need for the model itself. Any helpful suggestions would be greatly appreciated, thanks.

What program are you using? But the answer is proboably not, as that would take a physics engine and the usual Lego digital programs dont have that.
