Reply To: Force/Moment Reactions at Contact (Weld Seam Evaluation: nominal stress concept)

If it's worthwhile, APDL could be used as a check on the values in Mechanical.  I think it's possible that a small error in the centroid location could create a large error in the moment.  The APDL commands would be something like this:

cmsel,s,face   ! face is a named selection for the top flange face

esln                 ! is the tube connected by contact?  If so, this command will only select the tube elements and contact elements

spoint,,x,y,z     ! x,y,z are the coordinates of the centroid

fsum                ! Compare with Mechanical
