Overview Paulin Research Group (PRG) is a leading engineering software company that specializes in Finite Element Analysis (Design by Analysis) for pressure vessels. Knowledgeable engineers turn to FEA solutions from PRG when their vessel application exceeds the limitations of the ASME Code. Do you have external loads on nozzles where the shallow shell limitations of WRC-107 have been exceeded? Nozzles on shells where Rn/R exceeds 0.7? Cyclic fatigue loads? FEA software from PRG can handle these problems and more. To meet your FEA needs for nozzle to vessel attachments, COMPRESS offers FEA-Nozzles capabilities. FEA-Nozzles has been integrated with COMPRESS permitting FEA to be performed on nozzles from within COMPRESS with a few mouse clicks. Other Paulin products offered include All/PRO and FE/Pipe.
