Hi,

I need to compute max impact on glue constraints (call it max_impact), and use it to set glue constraint strengths such as: to break constraints set their f@strength<max_impact, otherwise set f@strength>max_impact. The idea here is to sim twice: first compute max_impacts on constraints, then sim a second time to glue strength either < or > than max_impacts. The problem here is each time I change glue f@strength, I get new max_impact? My initial thought is max_impact should be function of object density, speed,… and not related to glue strength?

Notes:

a-I compute max_impact by promoting impacts generating on constraints using “maximum” mode.

b-Below are 2 tests to demonstrate the “problem”:

Test 1: set Glue strength = 20e9 –> computed max impact on constraints = 2,879

Test 2: set Glue strength = 20e1 –> computed max impact on constraints = 286,801.8

As I mentioned above is max_impacts seems function of Glue strength? Attached is a simple hip file for the tests…

Thanks
