Hello again Everyone,
Can anybody give me an enlightment about when do we have to do Non-Liniear analysis in CAESAR II, I understand about single direction restraint, gap and friction if any of this in our modelling we have to do Non-liniear analysis, but i have seen my senior doing Liniear analysis even if he have a gap, friction and single direction restraint in his modelling, so i need another explaination when do we exactly have to do a Non-Liniear analysis in CAESAR II, coz if the system is so complicated contained of line with 2 piping spec., 3 pumps and PSV with gap and single directional restraint in the system and have a seismic activity and wind as an example maybe it will be so many case that i have to set in load case editor,it could be more than 99 load case.
