Hello everyone,

I have been doing a simulation with RBD's, it's a concrete tower who is being crashing with a meteor, I have set the ground as a terrain object, the base as static object, I used a pin constraint to try keeping the bottom of the tower over the ground but it still flying out, and the tower spins too much, I dont know if it's for the force of the hit, but I would like to do something more realistic, feel the tower is heavy. Thank you

you could do a lot of things to improve your simulation:

- increase the friction value of your objects
- play with the mass values
- slightly scale up pieces of your broken geometry to cause intersection
which is a hack to get the objects holding a little bit more onto each other
- create a drag force in your scene to damp out bigger velocities
- up the substeps if you're not happy with your collision results.

regards,

Manuel

thank you, manuel

about mass values, I am using density, you recommend use mass instead density?

And I dont undestand when you say scale, i am using Make BReakable, wheere do u scale the pieces?
