Hi everybody,
I don`t get the idea of tracking variables, I`ve studied at User`s Manual but I
still have problem.
I`m studying some contact laws due to this I need print or plot some output
data in order to compare these laws and in the future to analyze the empirical
results.
I used: PyRunner(command="AddData",iterPeriod=5)
from yade import plot
def myAddData():
b=O.bodies[1]
plot.addData(z1=b.state.pos[2], v1=b.state.vel.norm(),
i=O.iter, t=O.time) #OK, this worked!
But I don`t know if I must use a different kind of command for each variable
and how to use correctly the def.
I`m trying to print or plot normalForce, cohesion... in each interaction to
get some output data, but the error of: name 'command' is not difined, always
appears.
If anyone knows where I can find more information about the commands and defs
or a short explanation here, of the general idea, I`ll be very gratefull!
Thanks!!
