Re: [Bug 1026073] [NEW] "calm function" inside source code
Hi,
pkg/dem/Shop.cpp should probably be the right place.
As an example, you can have a look, how "Shop::getSpheresMass" [1] and [2]
was implemented, it can be also useful to keep "mask" parameter for more
flexibility.
Do not forget to add a python-wrapper for this function into
py/_utils.cpp [3] and [4].
Have a luck!
Anton

Title:
"calm function" inside source code
Status in Yet Another Dynamic Engine:
New
Bug description:
Hi,
I need a "calm function" for my generation process. In python code it
looks like this:
def calm():
for b in O.bodies:
if isinstance(b.shape,Sphere) or b.isClump:
b.state.vel = Vector3(0,0,0)
b.state.angVel = Vector3(0,0,0)
b.state.angMom = Vector3(0,0,0)
I detected, that it is very slow in the case it is called by PyRunner
for e.g. every 2 steps.
O.engines=O.engines+[PyRunner(iterPeriod=2,command='calm()')]
Would it be faster, when it is implemented inside C++ source code?
If yes, where can I implement it (which file)?
Regards,
Christian
