Hi, all
I modeled a spring-mass system in yade, using the remote interaction function
of JCFpmMat. But i want to change the value of the interaction forces during
the simulation. So I put PyRunner before NewtonIntegrator in O.engines, in
order to change the interaction forces before it was used for calculation. But
it seems it doesn't work out as I expected. parts of my script are as follows.
##################################################
def changeForce():
for i in O.interactions:
i.phys.normalForce=someValue # for example, someValue=(0,0,0)
O.engines=[
...
PyRunner(command='changeForce()',iterPeriod=1),
NewtonIntegrator(gravity=[0,0,0],damping=0.2)
]
##################################################
Thanks,
Zixuan Xu
