Question #232941 on Yade changed:

Jan Stránský proposed the following answer:
Hello Seungcheol,

yes, it means that something went wrong :-) Try to run the simulation step
by step (so instead of play button you use step button) and see if there is
some warning or errors..

at the beginning of the simulation and after each step (or a few steps) ou
can also check
for b in O.bodies: print b.state.pos
to see where the problems first occur (normally it should be normal
numbers, so when you see NaN, it is a signal of a problem).

Jan

PS: I just checked adding of Vector3 to plot.addData, so meybe the key
would not be 'b0displ' but rather something like 'b0displ_x'..
