i want use scipy within yade calculating a spline. but when i import
scipy.interpolate, i get a segmentation fault.
Yade [1]: import scipy.interpolate

, so it is
not feasable.
another way could be to use the 80bit long double of the cpu (core i7). how
can i compile yade to using this long double data type? or maybe double-double
arithmetics?

hi guys,
has anybody an idea, how the -l option works in batchmode?
yade-batch uses the -l option for something other.
i tried 'yadedaily-batch --job-threads =
rice flowing out of the hopper. These
simulation runs done with the same initialization. I guess this is
the numerically inaccuracy while solving the differential equation.
is there any option to reduce this error, except for running
replications?
