Zero Length Section Problem

I modeled a simply supported steel beam with a crack at bottom flange and I used zero length section element to model crack in beam (ENT material for bottom flange in fiber section modeling of section at damage location). In mode shapes of this beam i see a jump at location of zero length section el...

Health monitoring simulation

How can I model a beam with crack at its bottom? When dynamic load apply on it crack opens and closes

Thanks
