this is the question of pump suction line-eccentric reducer.
after caesar 4.4 version caesar has facility to model reducer
here i want to know if we model a eccentric reducer in pump suction line(top discharge-end suction),we found that at pump nozzle there will be a minor displacement(0.0002")vertical upward direction.as far as vendor allowable is concern we are not able to rich that allowable loads given by vendor(specially fy),due to that vertical eccentricity.
so my question regarding to that shall i model concetric reducer instead of eccentric in that case?

thanks in advance
