Ask HN: 3D physics simulator to fix custom wooden table

Hello everyone,

When I am not working, I like to play the carpenter... Yesterday I finished building my first folding table, with a custom design I was so proud of. Unfortunately, once I was done I realized that the table is very wobbly. It looks like something generates a lot of torque on the legs (made of wood). I tried to make them stronger by adding some steel plates, but it didn't work.

Before attempting more fixes, I'd like to simulate via software what would happen (for example: replacing wooden legs with steel legs). But I don't know of any 3D physics engine that would allow me to do this kind of simulations.

Do you know something that might help me?
