I am modeling a rockfill dam under seismic loads using the plastic hardening model with small strains. The dam is built under a given construction sequence, which generates strains and modulus degradation. I would like to be able to reset the deformations after the end of construction without reseting the modulus to G0, which appears to happend if I use
zone gridpoint ini disp (0,0,0)
as this does reset the strain increments and makes my model stiffer. Is there a way I can reset the deformations without reseting the strains or maybe just not reset the modulus to its initial values?
Thank you in advance,
