[Bug 505523] Re: Velocity Bin

 

Attach your simulation. Likely it is problem on your side with
simulation going nuts numerically.

One of common causes of NaN velocity is having body with zero mass
dynamic (such as a facet), which gives inf acceleration etc.

BTW if you don't know what NaN is, check
http://en.wikipedia.org/wiki/NaN .

I have the following error:

614459 FATAL yade.VelocityBins /home/chiab/yadeNew/Branch3/pkg/common/DataClass/VelocityBins.cpp:77 setBins: Body #1998, velSq=nan not put in any bin!?

Also, global stiffness timestepper seems to give me an exceedingly large step.  Sometimes 1e(positive)8!
