Hi Eric,
I just did a very simple test. The numerical values I see in ENFO,SUM and ENFO,VECTORS post processing objects in Mechanical are identical to the numbers I get with the NFORC command. You can create a static image with a post processing command object... /show,png $/pbc,nfor,,1 $/pnu,node,1 $eplot. I tried /pnum,sval,1 - the numerical values of the nodal forces did not appear on the static image as I had hoped, but with nodes shown in the plot of nodal forces, I could compare the static MAPDL imag, the NFORCE listing, and the ENFO,VECTORS image created by Mechanical. From where I sit, they all seem to be in agreement.
