Question #154219 on Yade changed:
https://answers.launchpad.net/yade/+question/154219

honzik proposed the following answer:

Hi Arthur

The NaN values are default ("given automatically") and the user is supposed to set real values to them (nan values are checked and if they are really nans, '!isnan(epsCrackOnset)' check fails resulting into
5731  FATAL yade.Law2_Dem3DofGeom_CpmPhys_Cpm /home/arthur/yade/yade/pkg/dem/ConcretePM.cpp:206 go: Verification '!isnan(epsCrackOnset)' failed!
