Not getting time history plot

Hello All,

I am trying to analyze an impact problem in Abaqus. I need to extract different time history plot. Sometimes, I am just getting a single point rather than any time history (Pic attached). I’ve just done some re-meshing of plate as well as impactor. I’ve done some modification (removed partition to re-mesh) in the impactor at part level. However, after the modification I’ve regenerated the feature, defined all sets and surfaces again. Before this modification, from the same model I was getting time history plot. Does anyone have any idea why does it happen? Thanks in advance for your kind help.
