dear all
i am having model that hot-tapping from pipeline that goes to vessel
i modeled as recommended in oct96 coade news that is new section model with installation condition restraint location only, existing pipeline with operating condition anlyzed in thermal case, found displacements imposed in new section restraints, but my case it is connected with vessel
my doubt is during thermal analysis new section installation condition weather i have to remove restraint at vessel bottom side anchor also and weather i have impose displacement on vessel bottom side anchor , pls guide me how to do when it is connecting with vessel

regards
pipeman
