Use of Bullet Physics to Rckfall Hazard Simulation

[egeo]

Recently I know Blender and Bullet Physics.
Bullet physics seems to have enough ability to apply for simulation of Rockfall hazard.
I studied this forum and internet, but a didn't fnd any dcument which is about application of Bullet Physics or any other Physic Game engine to Rockfall hazard.
Is there any problem applling Bullet Physics to Rockfall hazard simulation?
Or Engineers in this field just don't now about Bullet Physics?

It seems DDA and DEM method are common in Rockfall Hazard simulation.

DDA(Discontinuous Deformation Analysis)
DEM(Discrete Element Method)

Thanks in advance.

It can be used, but bullet and other physics engines generally aren't used for these sorts of problems because they are designed for stability and speed, not accuracy. You will get better accuracy with traditional methods.

Thanks for your reply NickoPen.
I see the difference is accuracy and speed.
It sound for me that bullet is good enough to apply for Natural Rockfall Hazard simulation.
Because the largest problem of Rock fall Hazard(or any of natural slpole Hazard)simulation is that we can't give parameter accurate enough not the acuracy of simulation method.
We can't know the exact　friction delive from the slope with woods for examlple.
