FESIF is a finite element based program that automatically calculates stress intensification factors (SIFs) and flexibility factors for a wide range of piping intersections not covered by the B31 piping codes. B31.3 states that for certain intersections, “selection of the appropriate SIF is the designer’s responsibility”. FESIF automatically produces these “appropriate SIFs” for geometries where the B31 codes are not suited.
FESIF v2.7 is an SMS-dependent module and is only available with an active support agreement for either FEPipe or NozzlePRO. It is not sold as an independent program.
